So, just to update everyone again, the problem is caused by an update to one of the plugins we use on the website for licensing the app. The update seems to contain a bug and does not complete correctly. I’ve tried a few times and got the same result so for the time being, I’ve restored things from backup (PSA: always have backups guys!) and will contact the plugin vendor on Monday (it is the week-end after all) to see what is going on.
Things should be back to normal for now. There may be some disruptions on Monday as we try to complete the update again.
I’ll leave this thread open so people can report on current success/issues.
Sorry for the inconvenience guys. I’m going back to my week-end activities now
