Also, please note it can take a couple days for any changes or updates you made to appear on search engines. Right now it probably still appears only as your old address.
Wait a few days, see if it updates. Then let us know of the results.
if you change your address you will have to also update your google account to the new address and the meta tags on your forum to match as this will no longer be working.
also Google can take up to 5 days to find your site and list it in google and i have seen this to take even longer.
