I upgraded to 3.1 and while it seems like all my info is intact, I'm having some very serious problems. First of all, the "if" sequence in my php isn't sending to the right single files anymore. Trying the new system of single-CUSTOMPOSTTYPENAME.php doesn't seem to work either.
Second, I liked the permalink structure /POST-TYPE/post-name/. Is there any way to get that back?
Perhaprs most importantly, wordpress won't let me edit any of my custom posts anymore! It's as if they were created by another user and I don't have permission!
The content is still displaying fine on the index page, but the single books just defaul to the index again.
