Yes, I hear you bro! It is frustrating. And yes, I did not bother to search the Joomla! forum about the problem. I did not post the problem either because my suspicion is not Joomla’s problem but specific to your web host server’s configuration.
To avoid the “Admin Access Denied” problem, I want to remind you once again to please avoid using your account at the frontend. The screen shot below is the frontend.
Frontend: Please avoid this area! You can create another account for this one if you want.
Remember the following posts?
Reminder: Starting today use “that” account at the backend only.
Backend: Please use this area only!
