[otrs] 2 slashes in address field (http://myserver//otrs/index.pl)

Hi all, I have a big problem. I install OTRS in my web server, and works fine. But, when i post any form, the system changes *http://myserver/otrs/index.pl *to *http://myserver//otrs/index.pl*, and browser shows page not found. I search in the system and find the variable $Env['CGIHandle'], witch manipulates this process, but i dont find where change this. This happens in any forms, even in customer.pl, or faq.pl. Someone have a tip? NOTE: in my local virtual machine system works fine. My server is a Fedora 4, and my local machine is a slackware 10.2. Regards, Daniel Rocha
