Hi all,
Thanks for the reports. It looks like at one time XCache (which the server uses for PHP cacheing) had a failure that needed manual intervention to resolve. Everything is up and running again now...
Shay: Unfortunately, there's a long-standing (2 years now since it was reported) bug in WordPress, whereby if WordPress can't find an update for a Premium plugin, it offers you a free plugin instead: https://core.trac.wordpress.org/ticket/23318 - the only thing to do is look at the update that it's offering you closely, and see if it has links back to wordpress.org (free version) or not. Also, it helps to know that UpdraftPlus paid versions have 4 elements in the version number; free versions have only 3 (e.g. 1.9.46 - current).
Once again - thanks + sorry to all. We're up again now.
Best wishes,
David
