Fixing WordPress 3.1 404 Errors

29 Mar 2011, Posted by Jessie Canon in PHP, Web Development, WordPress

I’m still loving all of the new features in WordPress 3.1, even though I have run into a few snags. After updating one of my client’s sites, I noticed that every single page and post was giving a 404 error. I did all of the usual things, checking my .htaccess file, made sure mod_rewrite was working etc… After seeing it wasn’t any of those I decided to disable my plugins to see if that was causing the problem, and YES!

If you are experiencing 404’s in WordPress 3.1 follow these steps:

  1. Disable all of your plugins and see if that is the root of the problem.
  2. Turn your plugins back on, 1 by 1 until you find the offending plugin.
  3. Empty your WordPress cache.
  4. Go to “Settings”, “Permalinks” and press save. This will refresh your permalink structure.

For me, the offending plugin was “Top Level Categories”. Glad that’s over with!

    I’m truly enjoying the design and layout of your website.
    It’s a very easy on the eyes which makes it much more enjoyable for me to come here and visit more
    often. Did you hire out a designer to create your theme?
    Exceptional work!
