MyBB Community Forums

I use 2 Mybb forums, both 1.6.7.

If I ban somebody, on the first forum the banned person is getting a red message in de top of the page that says he/she is banned.

On the other forum this banned person does'nt get this red message but a error-code appears:

The following warnings occurred: 

Warning [2] array_merge() [function.array-merge]: Argument #1 is not an array - Line: 295 - File: inc/class_session.php PHP 5.3.10 (FreeBSD)

File                          Line                             Function

/usercp.php                        21                require_once 

Does somebody knows how to solve this?

Thanks in advance,
