1.49 WebUI Doesn't Load

Since the update we haven’t been able to load librenms, the page just opens to a blank screen or HTTP 500 depending on the browser. We are on Ubuntu 18.04 and migrated to PHP7.2 to prepare for this update.

[OK] Composer Version: 1.8.4

make sure you have removed the old php packages.

Also, if running with nginx, remember to change sock file in your conf (nginx librenms.conf)
