OK, problem is your using a subdomain for your forums, which is known to cause issues with scripts like this (vB security related Im told).
There is a couple of things you can try.
1st, in login_inc.php change the paths to this format
Code:
http://www.nrlleague.com/forums/
I noticed you can reach your forums with both URL's so give that a go first.
If you have no luck with this approach then try this
https://vborg.vbsupport.ru/showpost....1&postcount=27
then if that fails, try this
https://vborg.vbsupport.ru/showpost....1&postcount=34
Let us know how you go.
