So on a server running php 5.5.36 I am continually running into an issue where things like store import or site upgrades just redirect to blank pages. I have no errors in error_log, apache or anywhere else I can think to look. If I set dev mode, I still just get a blank page.
Is there some weird flag I'm not flipping or something?
Example output:
{click upgrade, validate store path or whatever}
right this is on a 4.3.6 install and also trying to upgrade from 4.2.2 - > whatever is next
