WordPress error: Call to undefined function require_wp_db()

This started with the white screen of death. I cannot even get into wp-admin. I did not upgrade WP, did not load a new theme or a new plugin. Here is what I tried to fix it:

  • shutting down plugins
  • removing my custom theme
  • defining bigger memory in wp-config
  • removing white space in functions.php (even though I haven't touched it)
  • put error checking in wp-config. I get the errors:

Fatal error: Call to undefined function require_wp_db() in /home/youradmi/public_html/wp-settings.php on line 273

I started with the "Call to undefined function require_wp_db()" since it occurs first. Here is the line:

 require_wp_db();

Any ideas?

Do you know if the PHP version was updated? - Tomás Cot
Thank for answering. No PHP wasn't updated. - EK Blackwell
I contacted my web host to see if they updated PHP without informing us. - EK Blackwell

Sounds like you're running an older version of wordpress. I wouldn't worry about the deprecation messages. As Tomas suggested, your php version may have been updated. Those are just warnings meaning that at some point that code will stop working, but right now it will still work.

You could spend ages trying to figure out what went wrong, or you could just install a new copy of wordpress.

  1. Move all existing wordpress files to a subdirectory (e.g. 'backup').
  2. Install new wordpress
  3. copy backup/wp-config.php into new wp location
  4. copy plugins, uploads, themes from backup to new wp

When you login to the backend, your database will be upgraded automatically for the new version of wp.
