I have a very strange error in my wordpress wich suddenly appeared (well, i didn't noticed wich change was the cause) and i've couldn't guess wich is the solution.
See, in my blog I have more or less 30 active plugins, when I access to the "advanced options" in some of them, i get the error "You do not have sufficient permissions to access this page"
but it's strange because I get them only in few setup pages...
to be more exactly, in those plugin that create an extra menu below "Settings", like TweetMeme and WP-Polls
For example in TweetMeme that has 2 sub-menus, I can enter to the first option and make everything, but when I try to enter to the second one, I end up getting the error message and I can't do anything.
In WP-Polls that has 5 sub-menus, I can enter to the first, but I get the error in the other 4 sub-menus.
Up to now, I've installed another blog with the same plugins, and it doesn't get that error.
I've tried disabling all the plugins, one plugin at a time, but no matter which of them I disable, the error is still there.
I've re-updated the blog to 3.0.1
Change the database to an older backup
Googled a lot
but none of that has functioned
Could someone help me? Do someone know what could be going wrong with the blog or where should I look for a solution?
Thank you, all help will be greatly appreciated,
