* Hello,
* I’m getting this error today for a site that was working last week.
I suspect
it’s a server configuration issue but don’t well know where to look at… Any clues?
* Thnaks!

Please contact your hoster
and tell them why the loopback connection to** wp-cron.php **returns `This request
is not acceptable` error. Thank you!

* Tanks for your feedback.
There was indeed an issue with wp-cron.php but only
when running manual backups. Solved, with thanks!
