One hiccup I've noticed with WordPress is that when you use any plugin which removes the category base for posts and turn the plugin off, your posts will now return 404 errors. In addition, WP will continue to remove the category base - even though the plugin is deactivated.

Thus far, I've tested this with two plugins with the same result: http://wordpress.org/plugins/wp-no-category-base/


Is there a way to fix this?

    "any plugin" is pretty broad. What has this actually been tested with? – s_ha_dum Feb 11 '14 at 16:26
  • I updated the question to address which plugins this happens with (out of those tested). – AndrettiMilas Feb 11 '14 at 16:38
  • Did you try to re-save your permalinks (Settings » Permalinks) after you've deactivated the plugin? – Sven Feb 13 '14 at 22:50
  • Tried that @Sven – AndrettiMilas Feb 13 '14 at 23:43
  • What version of WP are you running? Did you put the plugin in plugins dir or are you using it within your theme? – Sven Feb 14 '14 at 9:51

This question was most likely down voted because the answer is in the plugin support forum. As stated by others in the comments, set default permalinks and save settings. Clear cache. Set permalink structure to what you want and save.

Also, feel free to look in the database.

where is permalink info stored in database?
