i kinda forgot how to install wakaba zero....
could someone tell me how?

Not unless you're more specific. Unpack and edit config.pl?

Also, http://wakaba.c3.cx/docs/docs.html.

ok i got everything uploaded and permissions set now how do i get it to run?

Point your browser at http://.../wakaba.pl?

i get an error... see......

If you have access to an error_log, look at that. Otherwise, it usually means you either have the wrong permissions (wakaba.pl should be 755), or the wrong hashbang (the #!/usr/bin/perl line at the start - usually this is correct, but on some servers you have to change it. Many Windows servers want it to be just #!perl).

Also, this is a useful thing to try: http://wakaba.c3.cx/sup/kareha.pl/1102836129/6

ok it turned out that host was crap, but i got a new one with cpanel and installed it and everything, and got error 500 when i went to wakaba.pl in my browser when i checked the error log i got a 'premature end of script headers' error

Same error, same procedure.

ok.... i tried that but i still get the same error. how do i fix it?

Well, 500 errors can be caused by all kinds of things. You'd have to ask your admin, probably.
