Redirection from subdomain to new domain htaccess

Hi everyone,

I’m a bit stuck on this and would really appreciate some help.

Basically I had the forums of a site I run setup as a subdomain, so they were accessible at

I have since spun out the forums into their own site with their own domain, but I just can’t get the redirection to work properly.

Currently I have an htaccess in the subdomain with a 301 redirect to the new and so when people go to the redirection works perfectly.
The problem arises if people then visit as they seem to get redirected to domainforums.comforums which obviously doesn’t work.

Thanks for any help.
