I use auto_prepend_file within .htaccess to insert tracking code into a vBulletin forum. It’s been working perfectly for more than two years, spanning vB versions 3 & earlier version of vB 4.
I recently upgraded that forum to the most current version and now the auto_prepend_file functionality is returning incomplete pages.
Specifically, the pages end in the middle of an HTML comment, with the last few HTML lines of the pages missing. All pages end exactly at the same spot from what I’ve seen so far.
I’m having trouble figuring out what the cause is. Pages load normally when auto_prepend_file is disabled in .htaccess (commented out) and load incompletely when it is enabled.
Any suggestions on what I should look into or ideas on what might be the cause?
