Foren / Cotonti / General / url !!!

I need that
my url being in
in: http://sova.ir/cotonti//list.php?c=articles
to: http://sova.ir/cotonti/articles

Open or create .htaccess (in Cotonti root)
Make sure it contains this:

RewriteEngine On

Below that, add this:

RewriteRule ^articles$ list.php?c=articles [NC,NE,QSA,L]

Now open datas/urltrans.dat and add this line at the top (before anything else):

list	c=articles	articles

Make sure those whitespaces are tabs, not spaces
