Tried in Firefox 3.6.8 and IE 7.0.6002

(Happens on my site and this one.)

confirmed on 2 sites as well..

i also disabled the tweet / FB buttons and still doesn't work

Party poopers spoil the release!

Checking on the problem now.

Sorry 'bout that
I was made up that the upgrade went so smoothly...

scripts/newreply.inc.php is my 1st guess

Variable got chopped out of showflat. Line 1366 of scripts/showflat.inc.php has this:

$smarty->assign("qboard",$qboard);

Right after that, add this:

$smarty->assign("parentPost",$topic_info['POST_ID']);

Patching up 7.5.6 in the download area now.

cool

and the fix works on my sites..

Doubly confirmed
(...but from a trusted source this time )

Cheers matey

So has this patch been migrated to the members area yet?

I've just checked the file I've just installed and the line is there.
