I would like to switch over form vBulletin 4 to Xenforo. But, I am running into some issues. I upgraded my PHP to 5.6.21 and then I uploaded the php checker and ran into the problem shown in the attached image. I then went to make sure these extensions were installed and they appear to be setup. Also, since I upgraded the PHP, my vBulletin is no longer working now... I'm in a bad situation! Appreciate any help you can give!
