Hello, I am trying to configure the ajax chat…
The installation was successfully, the tables are created (everything was created/installed perfectly)
Now, when I enter the chat and write some name and pass that is in my database, it is saying Invalid username (it is only logging with user: admin/user/moderator and pass: admin/user/moderator)

P.S. I tried to leave the config.php with everything null (at the mysql lines) + tried with adding my mysql database info in that lines

Some help!?
