Just curious as to what the difference between the built-in joomla SEF, and Artio SEF is? I run my site with the built in joomla SEF with mod re-write and url suffixes flawlessly... Jusr curious what the advanteges are is all.
the problem has been identified and fixed by Artio.
Just downloaded the latest JoomSEF Kunena extention published today and now I can run the forum with JoomSEF switched on.
