Mine is working and my ticket with SG reflected the same.
Siteground had provided a hotfix for my site while they are fixing the root cause.
Add this to wp-config.php
/** Sets up WordPress vars and included files. */
require_once ABSPATH . ‘wp-settings.php’;
#@include_once(‘/var/lib/sec/wp-settings.php’); // Added by SiteGround WordPress management system
>> Note that they had commented out the original code auto-added by SG and replaced with an ABSPATH code instead.
I’m waiting on the finalization of the fix as we speak.
