After looking into this, I believe the cause of this error will lead to the affected BB-Codes not being updated by this upgrade step. Since the upgrade step involves changing the add-on ID from the XF2 add-on to a custom add-on, the BB-Codes will still be associated with the old add-on ID and XenForo will automatically remove them. You may notice that you have no wiki BB-Codes listed in the BB-Code manager.
To regenerate the missing BB-Codes, perform the following steps. In
src/addons/vw/vw/_core/controller/cp/area/vw.php, find:
Code:
return $this->reply_view('CP/Area', 'modify');
BEFORE it, add:
Code:
class Fake_View
{
public function explain() {}
}
$fv = new Fake_View();
vw_Hard_Core::install('Common')->do_bbcode($fv);
Then visit AdminCP > Wiki > Structures > Area Manager.
After visiting the page, you will notice that XenForo's BB-Code Manager now shows the missing BB-Codes. You can reverse that file edit now.
If you had made custom names for any of the BB-Codes, in the BB-Code Manager, make those changes again.
If you had made custom BB-Codes for specific wiki prefixes, check that those BB-Codes still exist. If they do not, visit the Prefix Manager and recreate them by entering them into the appropriate BB-Code fields.
This error message should now be fixed in build 003, which should prevent similar loss to BB-Codes in future attempts.
