Upgraded to 3.1.1
Before upgrade did back of DB and files. Also deactivated plugins.
Upgrade appeared to work without a problem.
However, an existing custom post type is not being recognized.
If I go to an entry in the custom post type and get the URL then paste the URL into the browser I get a 404 Page Not Found.
There are two entries in the custom post type and they both produce the same error.
Does anyone know if there are any known problems with custom post types in 3.1.1?
I looked around the forum but couldn't see any reports of similar problems.
These custom posts were working fine under 3.0.1
What would be the best solution to fix the problem. I'm believe that my only option is to try a manual upgrade.
Any suggestions would be much appreciated since I'm at a loss to know what might cause this problem
