I've looked through the archives and can't find a definitive answer for this question, even though it's been asked several times.

I created a new ad in Blab Classifieds. The photos won't load and the text changes I want to make won't "take", so I tried to delete the whole thing. I keep getting this message:

You do not have permission for this action!

I've tried logging out and logging back in, and nothing changes.

Any help is appreciated.
