Can somebody please help me. Whenever I want to test a function I get the error cannot find xyz.pl. Which files do I need and where?

You need to look in all directories for the different *.pl files. Example there ar *.pl files in the admin directory in your cgi-bin and also in the sub-directories of the admin directory. I set all my *.cgi and*.pl files to 755 -rwxr-xr-x and every thing worked, make sure all the directories are set to 777 drwx-rwx-rwx.

Ass you have found out and what the readme file shows is is a permissions issue

Thanks for your reply.
I did it. But there are so many required .pl files and directories, which are not in the .zip file like Files or Validator.pl. Do you have a list of all required PERL files and dirs??
