Upgrade error
 

I just signed on for another year of support and I am trying to upgrade from 3.8.2 to 3.8.4 so I upload all of the files in the new version just like always (no images version) and then go to run upgrade.php which forwards me to upgrade_383.php and then there is just a blank screen. I tried uploading them all again and nothing. Even tried Firefox and still a blank screen.

Any ideas what would cause this? I gotta upgrade!!
