Hi, there was or is a problem with the Autoptimize plugin.
If I disable that, everything goes back to normal.
Thank you for the helpful tip.
Hi Rikard,
First of all thanks for the quick reply :)
The affected website is: http://www.luera1959.de
I haven’t disabled the plugins yet. They were all there before and I haven’t been able to find any connection between the plugins and this message so far. But I would like to try it right away.
Maybe another hint:
When I am logged into the backend, does this message not appear in the frontend?
Greetings
Mikel
