Outage Alert Completed CP2 "500 Internal Errors"


I've had reports this evening of sites on the CP2 server returning frequent 500 Internal Errors. Upon investigation, it appears to be limited to sites running on PHP7.1 and PHP7.2

This started following the automatic update last night. I've since switched all automatic updates off on the other servers.

Bug report has been files with cPanel and Litespeed (someone else has also reported the issue on the Litespeed site)

PHP Fatal error: Unknown: Failed opening required
New Thread - ea-php71-7.1.16 causing 500 errors

The issue has been worked around by dropping the affected sites back down to PHP7.

I'll update this thread with more details as I get them from the bug reports.
