@vtxyzzy – Thanks for the reply.

I have tried that exact that exact thing and it does remove the posts from that category. However, it also then does something very strange.

All of the remaining posts (those that are not in category id=3) link to the same post (the first post of the removed category).

Does that make any sense to you?

Here is an example of a page I can access in the WP admin:
http://www.propsandpans.com/wp-admin/edit-comments.php

Here are some of the pages I cannot access:
http://www.propsandpans.com/wp-admin/edit-comments.php?page=akismet-admin

http://www.propsandpans.com/wp-admin/edit.php?page=wp-db-backup

http://www.propsandpans.com/wp-admin/admin.php?page=wp-gbcf/wp-gbcf_form.php

http://www.propsandpans.com/wp-admin/admin.php?page=wp-polls/polls-manager.php

http://www.propsandpans.com/wp-admin/options-general.php?page=all-in-one-seo-pack/all_in_one_seo_pack.php

http://www.propsandpans.com/wp-admin/options-general.php?page=wp-cache/wp-cache.php

I didn’t give actual links because they are within the admin panel, and can’t be viewed without login/password.

Here is an screen grab of the error: http://www.propsandpans.com/error.jpg

Thanks.
