Managed Backups and Snapshot of files (only files - database works fine) are failing with 500 internal server error in browser console on admin-ajax.php file
In error_logs there is this:
[Sat Nov 04 20:30:42.399434 2017] [core:error] [pid 25909] [client 109:50039] End of script output before headers: admin-ajax.php, referer: https://site.net/wp-admin/network/admin.php?page=snapshot_pro_managed_backups&snapshot-action=backup
Same error shows for the Snapshots.
We need Second Line Developers to look at this.
