URL error message

[Deadleg]

Hello, another newbie,
My problem is; I was posting, and being accepted, using subdomains until told this was a big no,no. I changed to folders and from that day to this HQ has given me the error message, "incorrect URL".
I have tried contacting you but have received no response. The latest site I posted was: http://pornwaters.com/pw20.index/
Am I getting a; 'you're barred sod off' message or am I just doing something wrong.
Thanks a lot,
Deadleg.

Hello Deadleg,

My script doesn't accept urls like this one, please try to use something like that: http://www.domen.com/folder1/folder2/index.html or http://www.domen.com/folder1/folder2/.

Hello Yahook, nice to meet you.
I'm not all that good at html, would:
blah blah.com/pw20/index/
do the job, and how would it affect all my other links or would I have to make new folders.
Thanks a lot
