Hello,
I write this here because if I post it on the webphoto creator's site then it can take quite long to get an answer.

I have installed webphoto on one site and it works just fine.

I have installed it on another site and all links outside of the admin area dont work.

Example:
If I want to upload a new photo and go to admin...webphoto .....add/edit category....press add photo....
the link is...
mypage.com/portal/modules/webphoto/index.php?fct=submit&cat_id=5
that works fine

when I am in the webphoto module it want to go to the link:
mypage.com/portal/modules/webphoto/index.php/submit/
That doesnt work.

Does anyone know the reason why the same program should work on one site but not on another one?

after disabling "Use pathinfo" it worked fine.

Strange that 1 site hosted by 3ix.org has no problems with that while the other site has problems.

I can only recommend not to go to 3ix for page hosting. Its nothing but trouble.
