Title: Critical Error-plugins are deactivated Last modified: March 17, 2022 --- # Critical Error-plugins are deactivated * Resolved [eissac](https://wordpress.org/support/users/eissac/) * (@eissac) * [4 years, 6 months ago](https://wordpress.org/support/topic/critical-error-plugins-are-deactivated/) * I’m using WordPress for the first time. A few days ago I installed the latest version, picked a theme and started customizing it. I am using Projectfx and pagelayer. * All was going well until yesterday when I got the critical error message, no email. I cannot log into my dashboard–I get the same critical error. I checked the core integrity and then tried to reinstall–it didn’t work. I tried to follow the instructions on wpbeginner and did get to my plugins folder and renamed it plugins.deactivated as suggested. Still nothing. * I have screenshots of all of this, but don’t know how to link them. I did copy the written bit, which was: `Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/cassandr/public_html/wp-includes/wp-db.php: 1788 Stack trace: #0 /home/cassandr/public_html/wp-includes/wp-db.php(724): wpdb- >db_connect() #1 /home/cassandr/public_html/wp-includes/load.php(561): wpdb-> __construct() #2 /home/cassandr/public_html/wp-settings.php(124): require_wp_db()# 3 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/ php/WP_CLI/Runner.php(1291): require('/home/cassandr/...') #4 /usr/local/cpanel/ 3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/WP_CLI/Runner. php(1212): WP_CLI\Runner->load_wordpress() #5 /usr/local/cpanel/3rdparty/wp-toolkit/ plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/WP_CLI/Bootstrap/LaunchRunner.php( 23): WP_CLI\Runner->start() #6 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/ wp-cli/vendor/wp-cli/wp-cli/php/bootstrap.php(77): WP_CLI\Bootstrap\LaunchRunner- >process() #7 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/vendor/ wp-cli/wp-cli/php/wp-cli.php(27): WP_CLI\bootstrap() #8 /usr/local/cpanel/3rdparty/ wp-toolkit/plib/vendor/wp-cli/vendor/wp-cli/wp-cli/php/boot-fs.php(17): require_once('/ usr/local/cpan...') #9 /usr/local/cpanel/3rdparty/wp-toolkit/plib/vendor/wp-cli/ wpt-wp-cli.php(31): require_once('/usr/local/cpan...') #10 Command line code( 1): require('/usr/local/cpan...') #11 {main} thrown in /home/cassandr/public_html/ wp-includes/wp-db.php on line 1788 Error: There has been a critical error on this website.Learn more about troubleshooting WordPress.

Thanks! * [Dion](https://wordpress.org/support/users/diondesigns/) * (@diondesigns) * [4 years, 6 months ago](https://wordpress.org/support/topic/critical-error-plugins-are-deactivated/#post-15470559) * The stack trace goes through WP-CLI and cPanel, so this is not an issue with the web-based WordPress install. Are you trying to install WordPress from the command line using hosting-supplied tools? If so, you should report the issue to your hosting company. * Also give some thought to installing WordPress using the latest release downloaded from: [https://wordpress.org/download/releases/](https://wordpress.org/download/releases/) * Thread Starter [eissac](https://wordpress.org/support/users/eissac/) * (@eissac) * [4 years, 6 months ago](https://wordpress.org/support/topic/critical-error-plugins-are-deactivated/#post-15470674) * Tech support updated mysqli and now I can log into my dashboard again. However, when I go to customize the site, I see the placeholders for a theme that’s not even listed and when I activate a new theme, the old remains. Anybody understand what’s going on? * This is a theme I had tried, btw, but it’s no longer listed in my WP themes. * Thread Starter [eissac](https://wordpress.org/support/users/eissac/) * (@eissac) * [4 years, 6 months ago](https://wordpress.org/support/topic/critical-error-plugins-are-deactivated/#post-15470684) * I forgot to say: I went back renamed the plugins files “plugins”, removing the“ deactivate” part. Don’t know if that worked. * [Vijay Hardaha](https://wordpress.org/support/users/vijayhardaha/) * (@vijayhardaha) * [4 years, 6 months ago](https://wordpress.org/support/topic/critical-error-plugins-are-deactivated/#post-15470694) * Will you be able to share screenshot of the problem to understand the it properly? * Thread Starter [eissac](https://wordpress.org/support/users/eissac/) * (@eissac) * [4 years, 6 months ago](https://wordpress.org/support/topic/critical-error-plugins-are-deactivated/#post-15470708) * It seems to be a problem with popularfx, so maybe I should go to that forum. I don’t know how to upload a screenshot here. Happy to if you could explain how. * [Vijay Hardaha](https://wordpress.org/support/users/vijayhardaha/) * (@vijayhardaha) * [4 years, 6 months ago](https://wordpress.org/support/topic/critical-error-plugins-are-deactivated/#post-15470723) * You can upload a screenshot of any public image sharing website like [https://snipboard.io/](https://snipboard.io/) and then copy the uploaded image link and add the link here. * Thread Starter [eissac](https://wordpress.org/support/users/eissac/) * (@eissac) * [4 years, 6 months ago](https://wordpress.org/support/topic/critical-error-plugins-are-deactivated/#post-15470737) * Thank you! I’ll keep that in mind for future reference. I think I’ve managed to get things up and running again. At least, I hope so.
