Had to do some huge server maintainance work during the day so we've had some downtime. Sorry about that.
vBulletin upgrade caused some issues with Tapatalk. Well some missing files because I forgot to reupload the Tapatalk plugin files after the upgrade
Anyway, I've upgraded Tapatalk to the latest version as well
EDIT: I think iPad is supported with the latest Tapatalk version, not sure and can't test since I don't have one. Can someone test it?
