Title: Custom Plugin Fatal errors Last modified: August 20, 2016 --- # Custom Plugin Fatal errors * Resolved [420DankStank](https://wordpress.org/support/users/420dankstank/) * (@420dankstank) * [13 years, 10 months ago](https://wordpress.org/support/topic/custom-plugin-fatal-errors/) * I had a custom plugin created, but the creator wont get back to me since the plugin is not working. * The website is [http://www.washingtonstatecannabis.org/patient-verification/](http://www.washingtonstatecannabis.org/patient-verification/) * The front end seems ok. In the backend, on the plugin admin page, it will not load a form to enter new data. Nor can I edit data that is already entered. * I looked at the script.error_log ; This is what I got: * ``` PHP Notice: Use of undefined constant DB_USER - assumed 'DB_USER' in /usr/home/wash20/www/htdocs/wp-includes/wp-includes/wp-db.php on line 1592 PHP Notice: Use of undefined constant DB_PASSWORD - assumed 'DB_PASSWORD' in /usr/home/wash20/www/htdocs/wp-includes/wp-includes/wp-db.php on line 1592 PHP Notice: Use of undefined constant DB_NAME - assumed 'DB_NAME' in /usr/home/wash20/www/htdocs/wp-includes/wp-includes/wp-db.php on line 1592 PHP Notice: Use of undefined constant DB_HOST - assumed 'DB_HOST' in /usr/home/wash20/www/htdocs/wp-includes/wp-includes/wp-db.php on line 1592 PHP Notice: Use of undefined constant WP_DEBUG - assumed 'WP_DEBUG' in /usr/home/wash20/www/htdocs/wp-includes/wp-includes/wp-db.php on line 502 PHP Fatal error: Call to undefined function is_multisite() in /usr/home/wash20/www/htdocs/wp-includes/wp-includes/wp-db.php on line 505 PHP Fatal error: Call to undefined function _deprecated_file() in /usr/home/wash20/www/htdocs/wp-includes/class-snoopy.php on line 6 PHP Fatal error: Class 'SpellChecker' not found in /usr/home/wash20/www/htdocs/wp-includes/js/tinymce/plugins/spellchecker/classes/PSpell.php on line 10 PHP Fatal error: Call to undefined function add_action() in /usr/home/wash20/www/htdocs/wp-includes/theme.php on line 1170 PHP Fatal error: Call to undefined function add_action() in /usr/home/wash20/www/htdocs/wp-includes/taxonomy.php on line 100 PHP Fatal error: Call to undefined function feed_content_type() in /usr/home/wash20/www/htdocs/wp-includes/feed-atom.php on line 8 PHP Fatal error: Call to undefined function add_shortcode() in /usr/home/wash20/www/htdocs/wp-includes/media.php on line 707 PHP Fatal error: Class 'Walker' not found in /usr/home/wash20/www/htdocs/wp-includes/post-template.php on line 974 PHP Fatal error: Call to undefined function add_filter() in /usr/home/wash20/www/htdocs/wp-includes/user.php on line 72 PHP ``` * I’ve tried going in to put ‘quote’ marks around the db_user, etc. However, that did nothing. I tried downloading the newest version of WP and copying the wp_setting. php and the vars.php files over, and that completely erased the site, and added more errors. * Now my errors_log still has the errors listed above, but also: * ``` Fatal error: Call to undefined function _deprecated_file() in /usr/home/wash20/www/htdocs/wp-includes/wp-includes/theme-compat/comments-popup.php on line 10 PHP Warning: require(/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Fatal error: require() [function.require]: Failed opening required '/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php' (include_path='.:/usr/local/php5/lib/php') in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Warning: require(/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Fatal error: require() [function.require]: Failed opening required '/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php' (include_path='.:/usr/local/php5/lib/php') in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Warning: require(/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Fatal error: require() [function.require]: Failed opening required '/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php' (include_path='.:/usr/local/php5/lib/php') in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Warning: require(/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Fatal error: require() [function.require]: Failed opening required '/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php' (include_path='.:/usr/local/php5/lib/php') in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Warning: require(/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Fatal error: require() [function.require]: Failed opening required '/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php' (include_path='.:/usr/local/php5/lib/php') in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Warning: require(/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Fatal error: require() [function.require]: Failed opening required '/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php' (include_path='.:/usr/local/php5/lib/php') in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Warning: require(/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Fatal error: require() [function.require]: Failed opening required '/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php' (include_path='.:/usr/local/php5/lib/php') in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Warning: require(/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 PHP Fatal error: require() [function.require]: Failed opening required '/usr/home/wash20/www/htdocs/wp-includes/class-wp-theme.php' (include_path='.:/usr/local/php5/lib/php') in /usr/home/wash20/www/htdocs/wp-settings.php on line 115 ``` * I’ve since removed my changes, and am back at square one.

Mixing and matching files from different releases will cause trouble. Please put things back the way they were. * When did the plugin stop working? Did you do anything? Add another plugin? Change themes? Update WordPress? * Post your plugin code to the [pastebin](http://pastebin.com/). Maybe someone can spot the problem. * Thread Starter [420DankStank](https://wordpress.org/support/users/420dankstank/) * (@420dankstank) * [13 years, 10 months ago](https://wordpress.org/support/topic/custom-plugin-fatal-errors/#post-2887852) * I am running the newest version already. I thought that when I did an automatic upgrade, maybe things didn’t get copied right. At least, that is what I have been reading on other forums regarding similar problems. * The problem happened back in May. I got injected with malware. I completely wiped the site. Deleted everything from it and started over. Reinstalled wordpress and uploaded a backup from a week before the injection. Installed a f*ck ton of security measures after that. * It wasn’t working after the upload, so I tried changing themes. No help. Changed it back.

Instead of just copying a couple of select files, re-upload the whole thing– all the WordPress files from the same release as you are already running. * What are those security measure? Something may be causing a conflict. You may want to try disabling those one by one to see if it makes a difference. * Nothing in the code stands our as especially weird, and none of it looks obviously related to that plugin. If it were me, and the stuff above doesn’t help, I’d start commenting out pieces of that to try to find what is triggering those errors. * If you don’t already have debugging enabled, switch it on. It may provide a clue. Add `define('WP_DEBUG',true)'` to your wp-config.php. * Thread Starter [420DankStank](https://wordpress.org/support/users/420dankstank/) * (@420dankstank) * [13 years, 10 months ago](https://wordpress.org/support/topic/custom-plugin-fatal-errors/#post-2888002) * So, since I last posted about having this WP problem, my computer crashed cause of the S.M.A.R.T. HDD virus. I recovered from the virus, but delete my video drivers and couldn’t boot BIOS to fix the problem. Had to have it taken in to be repaired. I’m going to try to work with the WP_DEBUG option today. Hopefully I can find something there. I feel like it is the DB that is just not defined or something. I’ll let you know what I find in a little bit. * Thread Starter [420DankStank](https://wordpress.org/support/users/420dankstank/) * (@420dankstank) * [13 years, 10 months ago](https://wordpress.org/support/topic/custom-plugin-fatal-errors/#post-2888005) * So after I put the WP_Debug in the wp-config.php, what do I check out then? I looked at the script error logs again, and now there is only one: * PHP Fatal error: Call to undefined function add_action() in /usr/home/wash20/ www/htdocs/wp-includes/wp-includes/update.php on line 337 * I checked out the update.php and on line 337 is: add_action( ‘admin_init’, ‘_maybe_update_core’); * Thread Starter [420DankStank](https://wordpress.org/support/users/420dankstank/) * (@420dankstank) * [13 years, 10 months ago](https://wordpress.org/support/topic/custom-plugin-fatal-errors/#post-2888012) * Ok, so far today, I checked out the WP_DEBUG. I fixed most of the Notice errors. My theme must be old, cause it had a lot of errors for ‘get_settings’. I had to change all of those to ‘get_option’. I then had to add an extra line in each of the Theme php pages: `{ if(isset($value[‘id’])`) before the ‘get_option’. * I also had to delete 3 of my plugins cause the were causing errors. Google Maps, Updraft – Backup/Restore, and WP Mobile Pack. * I’m now left with only a few errors. Two main ones that I can’t figure out: * Missing argument 3 for wp_register_sidebar_widget(), called in /usr/home/wash20/ www/htdocs/wp-content/themes/connections-reloaded/functions.php on line 152 and defined in /usr/home/wash20/www/htdocs/wp-includes/widgets.php on line 604 * and * PHP Notice: get_settings is **deprecated** since version 2.1! Use get_option() instead. in /usr/home/wash20/www/htdocs/wp-includes/functions.php on line 3467 * For the PHP Notice, I went to the file that it mentions, and on line 3467 it only says:` trigger_error( sprintf( __(‘%1$s is deprecated since version %2$s! Use %3$s instead.’), $function, $version, $replacement ) ); * The whole line of code that it is referring to is:` // Allow plugin to filter the output error trigger if ( WP_DEBUG && apply_filters( ‘deprecated_function_trigger_error’, true ) ) { if ( ! is_null($replacement) ) trigger_error( sprintf( __(‘%1$s is** deprecated** since version %2$s!
