I also have this problem what I saw posted at least err.
2 times on this thread, and NEITHER had a post answering the trouble.
I am trying to install Kareha (and wakaba once, same problem)
I have two machines, one is a host I have remotely, and one is a basic linux (desktop) with apache installed by me and it works.
When I use on my local machine I can physically touch, to say, and access Kareha.pl on web browser, I see the code, if I try install it on the remote host I have, it gives me a download window to save the Kareha.pl file.
I also added the perl exec CGI thing but from other stuff I dunno.
Could someone answer with the "only show's code and does nothing" when accessing the #.pl in browser?
Thank you.
