I have categories on the back end. I removed the Uncategorized category. Categories suddenly stopped appearing on the front end EXCEPT they are visible as selections when creating a new post.
When the new post is posted, it generates a 404 error.
The new post becomes visible in the Jomsocial stream.
Clicking the post link generates a 404 error.
This site needs to launch in two days. This was really unexpected. Can I get some help?
