WordPress 3.0 Can’t Edit Posts Issue

I had a weird WordPress 3.0 issue in one of our sites after doing an auto-upgrade.

I couldn’t

  • create a new post
  • edit an existing post
  • open up the collapsible menu in the side in admin
  • quick edit posts

Pretty much, it looked as if javascript had been disabled. I tried deactivating all the plugins and even renaming the plugins folder. I tried uploading the wp-admin and wp-includes folders manually to see if the auto upgrade missed copying the current version of files.

None of it worked. After browsing the WordPress.org forums, I came across a tip pointing to a particular db.php file in wp-contents folder. Renaming that file to db.php.0 worked!


  1. Go to wp-content
  2. Backup and delete db.php file if you have one.

It appears that plugins like DB Cache, DB Caching Reloaded, etc create this file which leads to unresponsive WordPress admin area. Hopefully, this will help some of you facing the same issue.

    Actually, K, it was probably just that the stored queries weren’t compatible. You should always disable caching before doing a WP upgrade and clear out the cache files. I’m running WP File Cache and Quick Cache at the same time on several blogs. No problems with either.
