Came here looking to see if the doublepost issue has been resolved with users running php5.4. All I have found are posts by others asking for the same resolution. Vbulletin has turned into garbage ever since it was sold. I have 4 licenses and each of them are being migrated over to Xenforo. Vbulletin really screwed themselves with this issue seeing as it has been OVER A YEAR! I really wish I never invested any funds in this garbage.
