When logging in, the user is just redirected.

Okay, this is getting a bit confusing. I made two more accounts. The first account was fine, but the second one had the SAME error. I also looked under the comments on the codecanyon purchase page, and another person had the error. Could you provide me with the solution?

Please use the attached updated version of script just re install it and don't forget to change the DB details in Script >> Lib >> Includes >> Deb_connect.php file

Also check your User levels and their pages, which user level are you talking about? And check general settings also. If all is right. Otherwise send me your logins i will check settings. 

Thank you! It worked.
