What is the usercp2.php file for?
I keep getting this error:
Authorization code mismatch. Are you accessing this function correctly? Please go back and try again.
USERCP2.PHP is for Other Functions given by mybb like subscription of thread by user and blah blah... do not attempt to delete it.... you will be in trouble later on than
usercp.php is the frontend renderer; usercp2.php is the backend function calls.
I don't understand how do I use it?
The thread Yaldaram gave me link to doesn't help me to fix it? :/
You're not supposed to use usercp2.php, it's used internally.
