Hi, my problem occurs in some topics or categories of my forum, not all, but completely prevents me from entering certain urls, I had to disable the Kunena SefUrls, when I try I get the following error message (firefox):

"This page is not redirecting properly

Firefox has detected that the server is redirecting the request to this address in a way that will never end.

This problem is sometimes caused by disabling or refusing
the receipt of cookies."

but only comes out in some random links within Kunena, the other site works perfectly with SefUrls, even most of the links within Kunena work well, except those... well, my site is criticalhit.com.ar, i'm using Joomla 1.5.23. Thanks and sorry about my google translated english :D
