need help subdomain

[EasyGamerz]

Dear Community,

I have a little problem with the vbseo plugin. I found a vbseo plugin in the internet and installed it (I guess the last version from vbseo.com) so it was working fine, but now I got a new payment gateway which needs a ipn folder. So a friend installed that payment gateway and added a subdomain to our site -> ipn.domainname.com and we moved our forum to public_html.

And now the problem comes, our market script which is installed in domainname.com/market has to access that subdomain, but each time when it comes to that subdomain it redirects our user to domainname.com/market/ipn so this is not working how it should work. Is there a way to change this?
