 * So confused. I was editing one of my pages trying to get my site set up. I changed
   the name of the page I was editing, and then changed the way my blog organizes
   its permalinks. Immediately afterward, my entire blog became inaccessible, with
   this error:
 * Fatal error: Cannot use object of type WP_Error as array in /home/jinxville/public_html/
   welcome3/wp-includes/category.php on line 137
 * I have no idea what I did wrong, and I really don’t want to have to reinstall.
   I tried re-uploading a fresh version of category.php, but that didn’t do anything.
   But now I can’t even access my control panel to fiddle with the settings.
 * Any help?

 * agreed – I had this error after updating wordpress and my plugins and I can no
   longer access anything to disable it…
 * EDIT: I removed the plugins, and found it was actually a plugin that was causing
   all 3 of my errors found in /wp-includes/query.php and /wp-includes/categories.
   php
 * Once I yanked the plugin from the folder manually via FTP, everything was fixed.
   I’d recommend you make a duplicate copy of your /wp-content/plugins folder somewhere
   and then make a new one on your site and add them one-at-a-time to see if you
   can diagnose the offending plugin and then get rid of it or look for a fix for
   it? I’m not an expert, just trying to help out!
