#113 invalid username or password at admin.php

[Rank Beginner]

I've installed phpWiki 1.2.6 using an auto installer as
provided by my hosting, i.e. I just clicked the button
and it took care of the rest, but when I enter my
username and password to access the admin section at
admin.php it says "Invalid username or pasword" ... ?

Also, I installed it in the root of a subdomain, should
I have installed in the cgi-bin of the subdomain?

Thanks

I am having the same problem, could it be because the
program has no writing permissions?

I also have the same problem. However, my phpwiki is not installed under the root, but under my-domain.com/wiki
I tried CHMOD'ing all the subdirs to 777 in a desperate attempt to make it work, but still it doesn't.
