I really need some help.
 

I seem to have figured out my login issues between the forum and PP.

Everything looks good so far except.

In admin when I go to edit categories, I get this error. All other admin functions seem to work fine.

Thoughts?

Well, after several hours I found what the problem was so I'll post it here so others can find it.

adm-cats.php for some reason had different permissions than the other adm- files. I looked at it via ftp and saw the difference. Reset it with chmod and it was fine. Funny how one little thing can kill so much time.

Yes a php script by default needs to be 644 any permissions less than that and you can not access the file by web.
