As it happens so often I just tried adding a new field which worked like it should. After that all the errors are gone now.
Sorry for bothering you! Happy now 😉
Sorry…my bad! I switched themes and it worked!
So…sorry!
Hi Dennis and Elliot!
Thank you so much! Dennis! That worked for me, too!
Problem has been solved! Great job!

Hi elliot,
thanks for answering,
I have tried everything you suggested.
– Re-uploaded a fresh install of wordpress
– deactivated ALL plugins except acf
– switched to default theme
But still… Error remains ONLY on post.php when I am in edit mode for a page.
The custom fields work fine but some other things are broken.
Is there anything else I can do to get to the bottom of this? Otherwise I might just have to live with it…
Thanks again!
Anja
