The interim upgrade to vBulletin 3.8.11 has been completed, but surely many tweaks will still be needed. Please report any concerning issues encountered by PM or email to
ljones@vikingsword.com.
Please note that this new version will resize images of compatible types automatically to fit the forum size requirements.
It was not intended that the error message that you would have seen yesterday and earlier today would appear. In order to update the forum software, the PHP version first had to be updated, but the old forums software was not compatible.
