That's kind of a bogus error. The $VERSION variable was getting lost.
I discovered you needed to add $VERSION to the global call in the header or else you got it on the left.
I don't knwo why you'd get it on the right. $VERSION is used in the footer and already in the global call down there.
You can get around it by removing or commenting out this from the sidebarpal.php
if (!stristr($VERSION,"6.2") and !stristr($VERSION,"6.3")) {
$VersionNotice = "<br /><br /><strong><span class="standouttext">Version missmatch!</span> IIP $palVersion will not work with UBB.threads™ $VERSION.</strong>";
}
It's just the check that it's the right version of threads. But when threads upgrades, you'll most likely need to update the sidebarpal if you get errors.
once you take that out, it should get by it.
