Wrong and strange link when logging out
 

If i press the logout button, i get the screen:
Return to previous page
Return to forum index

The link to return to the previous page is correct.
The link to the forum index is this one:
http://www.myforum.nl/forum.php.php[ARG:3%20UNDEFINED]

That results ofcourse in an error page if you click on that.

Where can i edit this link?
In the ACP under Site name / URL / Contact details i have this as Forum URL and as homepage URL: http://www.myforum.nl

Note: I have changed the name of my forum in this post to myforum.nl

Go to the phrase cookieclear and see if it has a {3} in it. I think it should only have 2 parameters.

That solved it.
Had to search a little for the phrase, but the result is perfect.

Thanks
