Recently have login / permissions problem when logging into one of my sites that uses Drupal. Can login in using super administrator username and see all functions/ menu but when I click a function, it shows error "Access denied You are not authorized to access this page". Then I login again and can see all the functions but when I click for eg. Create content it comes up with error "create content You are not allowed to create content". Did not have this login problem a few mths ago. Stopped logging in for abt 1 mth and now when try to log in encounter this problem. Would appreciate if someone can advise how to solve this problem. Thanks
To confirm, the administrator account you are referring to is user ID # 1, if it's not, I dare say it's a user role issue.
Try clearing your browser cache. It looks like Drupal keeps logging you out (or your session expires) each time you attempt to access a function. This happened to me once and clearing my cache resolved the problem. Also, to be on the safe side, if you have look at your users and see if anyone else has admin functions. Make sure your user roles have not been fiddled with, which is highly unlikely.
