# PHP errors related to wp-db and load.php

 * I’m not a PHP connoisseur by any means, so when I saw this on a site I help out
   with, I was a bit puzzled:
 *     ```
       Warning: require_once(/home/content/66/4655366/html/islavistaworship/wp-includes/wp-db.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/66/4655366/html/islavistaworship/wp-includes/load.php on line 320
   
       Fatal error: require_once() [function.require]: Failed opening required '/home/content/66/4655366/html/islavistaworship/wp-includes/wp-db.php' (include_path='.:/usr/local/php5/lib/php') in /home/content/66/4655366/html/islavistaworship/wp-includes/load.php on line 320
       ```
   
 * Unfortunately, I don’t know the version of WordPress I’m running at the moment
   because I don’t have access to the server backend, just the login for the WP 
   backend. I’m getting the details from the folks who built the site so I can work
   on the backend (most likely going to need to do that).
 * Anyone have some ideas that can help me get things back on track once I get some
   FTP credentials from the owner?

 * Fatal error in the output generally indicates either: (1) your theme doesn’t 
   like your version of WordPress (2) you have a plugin that doesn’t like your version
   of WordPress (3) or you have an incomplete install/upgrade
 * Have you tried:
    – Flushing any caching plugins you might be running, as well
   as server and/or browser caches. Also, any op cache or content network cache,
   as well as Cloudflare, clear those caches. – deactivating ALL (yes all) plugins
   temporarily to see if this resolves the problem (plugin functions can interfere).
   If this works, re-activate them individually (one-by-one) to find the problematic
   plugin(s). – If you can’t get into your admin dashboard, try [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by [FTP](http://codex.wordpress.org/FTP_Clients). Sometimes, an apparently inactive
   plugin can still cause problems. Also remember to deactivate any plugins in the
   mu-plugins folder (if you have created such folder). The easiest way is to rename
   that folder to mu-plugins-old. – switching to the unedited default Twenty Fifteen
   theme for a moment using the WP dashboard to rule out any theme-specific issue(
   theme functions can interfere like plugins). If you don’t have access to your
   admin area, use [FTP ](http://codex.wordpress.org/FTP_Clients), or your web-host’s
   cPanel or whatever file management application your host provides. Navigate to/
   wp-content/themes/ and switch to the default theme by renaming your current theme’s
   folder by adding “-old” to the end of the folder name. Alternately, you can remove
   other themes except the default theme. That will force your site to use it. –
   If all the above steps do not resolve the issue, then try **MANUALLY** updating.
   Download a fresh copy of the WordPress .zip file to your computer, unzip it, 
   and use that to copy up all files and folders **EXCEPT the wp-config.php file
   and the /wp-content/ directory.** You may need to delete the old wp-admin and
   wp-includes folders and files on your server before uploading the new ones. Read
   the [Manual Update ](http://codex.wordpress.org/Updating_WordPress#Manual_Update)
   directions first.

 * Thanks Tara! I’ll give this a try as soon as possible. Those suggestions are 
   very similar to what I suspected — I’ve had errors like this on other sites before
   and they’re sometimes syntax but that’s unusual. I appreciate the help.
