vBulletin forum white screen page when inserting image or video
While working on a couple vBulletin 4.1.3 to 4.1.12 upgrades this weekend I ran into an interesting problem. One of the forums, besides needing an upgrade, was also experiencing a trouble where images and videos could no longer be inserted into posts. When the forum was running 4.1.3 the popup box for insert images would appear and then quickly disappear. After upgrading to 4.1.12 instead of getting a popup box a white tint (not a blank white page) would appear over the entire new post/reply pages. The forum did not have any additional products and had very little customization done to the standard vB4 style. After editing config.php and adding define(‘DISABLE_HOOKS’, true); as the second line the forum did indeed begin functioning correctly again. I checked the plugins and found an extra plugin named HTTP-Request that did not belong there. The forum had been hacked. I removed the HTTP-Request plugin and also did the diagnostics to remove a few extra files within the file structure that were not a part of vBulletin. I asked the owner to have all admins and mods change their passwords. The forum is functioning correctly again now the the problem plugin has been removed
