First time CentOS/centminmod user so bear with me. More of a debian guy. I just setup a fresh vps box with CMM, all good. Using latest 09LE branch, created a new vhost, set it up, tested with standard issue php 5.5, works well (even got an LE cert issued first time). Good job @eva2000 on the builds. Migrated a backup copy of my Xenforo 1.5 forum with a few addons. All works. So, proceeded to do a php 7 upgrade expecting some issues, restarted it all and I get an error 500, nothing in the page source, nothing in the error log for the site, no messages (in var/log). Clueless as to what addon/problem can cause this. Anyone with any tips on how to debug this? Should I drop in the PHP debug flags and check.
