3.8.4 won't run on php 5.2.12
 

I recently asked my host (VPS) to upgrade from php 5.1.6 to the newest version which was 5.2.12 . I am running 3.8.4 and when they did the site went blank. they installed 5.1.6 back on and it worked.

Is 3.8.4 not compatible with php 5.2.12 or is there something elese?
