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 by FTP. 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 , 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 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.
