“You don’t have permission to do that.”

Hi Support,

Forgive me if there is an answer to this issue already on the boards as I know it was a bit of a hot topic at one point. I have searched high and low but all threads keep pointing to the answer being in a link, with said link being long dead, dried and buried ??

I’m receiving the error message “You don’t have permission to do that.” whenever I try to delete or create categories, or delete posts etc.

What sort of things should I be checking in order to troubleshoot this issue? Are there any chmods I should be performing or checking? is it likely my db at fault or is it simply a bug?

Many thanks in advance,
Wazr
