Link Posting does not work
 

i understand that it works fine on the demo edition that vB has made available. but it has not worked on my test install on my server.

i just installed the latest beta 15. this is what happens. if i do not include a text in the message box it shows this error: http://i.imgur.com/IBdzU.png

if i add some text and then try to post, it just hangs. a working message comes at the top in a yellow box. but nothing works. even if i wait for minutes.

what can be the reason? i have tried a fresh install. has been same since the first public beta release. should i file this as a bug?
