Strange error Message, maybe someone has any idea...

- when NOT logged in, this will show only somewhere within Kunena Forum page
- when logged in, whis will show on the very top of each page and Kunena Forum

Exact Error message is:

Warning: preg_match() [function.preg-match]: Unknown modifier 'r' in /.../com_sef/joomsef.php on line 174

Page is www.mmoinfos.de
Forum page is www.mmoinfos.de/forum

Thanks in advance for any help!

Hello,

Open the Kunena extension parameters using the Manage Extensions page in JoomSEF and check your "Do not SEF URLs matching regular expression" field on the common tab.
