If you are getting website error messages while browsing MMG, please submit a contact ticket and let us know. We will do our best to help you figure out what the problem is. Usually this is very uncommon and only happens if a quick maintenance job is being performed.
If you are getting a message that says something like "you do not have permission" or "admin has not enabled permission", this is most likely because you are not allowed to do whatever you are trying to do :) If you feel this is happening when it's not supposed to, please submit a contact request.
