You haven't solved your problem though maestrodamuz, you've merely averted some symptoms. Check the top of your adminfunctions.php file and it will tell your the vBulletin version number of the file, (most definately will not be 3.7.x). You need to figure out why you're files are not being overwritten correctly. It maybe that you aren't uploading the correct files or to the correct place or it may be that there is something wrong with the FTP transfer/FTP Client.

You need to look into this as it will only cause problems in the future if core files are updated and you are using older files.
