Don’t panic, we’ve got a solution for you. It worked for me and hopefully it should work for you as-well.


You may get this get this fatal error if you have any plugin for database cache or something to do with WordPress database.

When this fatal error came up for me, I had DB Cache reloaded installed on my WordPress.


Solution to this Fatal Error:

Solution for this error is pretty simple.

  1. Open your Hosting Cpanel or use any FTP Client to browser wp-content of your WordPress installation.
  2. Now, locate the DB.PHP file and download it to your hard drive as a backup.
  3. Once you have backup up DB.PHP, just delete it from wp-content.

The page should now say “Update Complete”

  1. If you still get the same error, then, go to wp-content/plugins and backup DB-Cache plugin (compress it first) and delete it. And now it should work and you should be able to go to your dashboard and re-install Database cache plugin from your WordPress interface or restore the DB cache plugin folder which you backed up earlier.
Now you are good to go, take a deep breath enjoy WordPress 3.4 Update and keep blogging
