Hi all - I created a new add-on domain on my hosting account for a new zencart website. The URL is

http://www.ignitionformen.com.au/index.php

For some reason whenever I click any link on my site (whether it be a page link or product), the "webstruc.com.au" prefix appears in the URL. "webstruc.com.au" is the main domain for my hosting account.

After clicking a link this is the URL:
http://webstruc.com.au/ignitionforme..._page=products...

The correct page still loads, but I dont want this prefix to appear. Not quite sure what file needs to be altered. My hosting company doesnt know either.

Any help will be greatly appreciated.
