7.3 join page issues

Have anyone had these problems with 7.3 when a new member try to join the page freese and the member is unable to join? Is there a fix for this issue?

Are there any other sites using 7.3 without any issues?

It seems to occur in Chrome browser only?

try at demo.boonex.com - see what happens there. Is yours a fresh install? How did you do your install, did you use an autoinstaller?

tried some more:

the problem seems to occurs for first time user only. When visiting the page for first time/cleared cache the forum loads endlessly without a result and though modal box for join/login is not working.

After visiting the forum it will load and the modal works fine.
