I have been using wordpress 2.7 on 6 blogs since early December. Suddenly I am getting a You do not have sufficient permissions to access this page on the plugin install page for one of the six blogs.
I am logged in as admin.
This is the only page with this error, I can carry out all other admin functions including upgrades.
I have tried deleting and reinstalling the entire wp-admin directory but the problem persists.
I have done a search on You do not have sufficient permissions to access this page but the other posts are after a new upgrade and/or about lack of admin access site wide. I can't find information on access being prohibited on a single page.
