Forums / Cotonti / Support / Can not add, edit or publish pages.

If there's a .htaccess that is higher in the folder hierarchy (in place of xxxx or testers), check it out as well. The htaccess might be propagating to cotonti_testsite as well.

Also, manually change in database the url settings to "none" (in case the site tries to load something from urltrans.dat).

That's what comes to my mind...
