Well I just wanted to post here, incase anyone else is having issues that I have came across and took me a bit to figure out. I recently upgraded my dedicated server to php 5.5.10, before that it was 5.5.9 and a site I run for a customer is built upon larval 4, however I got the white screen of death, and I was at a lost. Well in a last ditch effort before I redid the whole site again for him, I figured well its already White screen of death........ May as well try to update larval and see what happens. Well after upgrading to 4.0.1 the site came back to life, so I'm assuming that larval 4.0.0 doesn't support the newer versions? Anyway just thought I would share in case anyone else is having this issue with the 4.0.0 branch!
