Hi, this is the first time I write, I hope not to write in the wrong section. My problem is the following: I uploaded a project in PERL - XSLT - XML, but something does not work and I do not understand what, and I do not know how to find out the reason. I have configured .cgi files with shebang line " #!/usr/bin/perl -w " first and " #!/usr/bin/perl " after, and set permissions 0755. Hello World works perfectly. http://www.pandora.heliohost.org/cgi-bin/prova.cgi However when I run the project i get 500 error. http://www.pandora.heliohost.org/cgi-bin/home.cgi Is there a way to have more detailed information on what does not work so I can understand where the error is?
