I have added this note in another subject but it seems that with the load of comments it became neglected or something. so I thought I should open a new thread for this problem specially after searching the forums and waiting for a week or so to get at least a comment of thrown idea of what i am facing now, I've been also trying other forums and searched the Internet so hard but no results .. I would appreciate any comment that might lead to something to fix this problem , because it took me a month to do the installation and build up what I got so far , and now I feel like falling apart with that access denied problem !!

basically the problem is that something happened and I can't access with a registered user-name and I can't register anymore. I can still access the Administration with absolutely no problem but I don't know what I should do now. All what happens that when I click on Register or Log in, it redirects me to a white-page with 'Access Denied' sentence only.

Please help me !
