Just to let you know, I managed to get this working on 3.6.4
I'm not positive if all the bugs are gone, but at least I can view and edit the blogs now.
In journal.php, find:
PHP Code:
$vbulletin->journal_opt = unserialize($vbulletin->journal_opt);
$setting =& $vbulletin->journal_opt;
Replace with:
PHP Code:
// $vbulletin->journal_opt = unserialize($vbulletin->journal_opt);
// $setting =& $vbulletin->journal_opt;
Haha, was that simple or what? I stopped getting database errors on my main page with this quick fix.
