So after I rebuilt apache through Easy Apache, I am getting 500 errors on all my sites, even the ones that are not on xenForo. Which means that it probably has nothing to do with the requirements of xenForo. All my databases are on a remote mysql server, however that would display something like "A database error has occurred" on my xenForo page. So it seems that apache is the main problem at this time. I looked into the error logs and all I see is the following [Sat Sep 08 01:45:54 2012] [error] [client IP ADDRESS] Premature end of script headers: index.php Which doesn't give me enough information, or any at all. I also had this error PHP Deprecated: Comments starting with '#' are deprecated in /usr/local/lib/php.ini on line 1071 in Unknown on line 0, referer: My Website URL. I removed that line and that error stopped popping up. Besides these two errors I am not getting anything, so I am not exactly sure what's wrong. Any help would be appreciated.
