Hi Robert,
Thank you.
It turned out to be one of the plug-ins Customify or Content Cards. I disabled them, and now the edit field is accessible again.
Thanks for your help!
Best regards,
Jan Westerhof
Thanks. The issue no longer exists.
I hear from a friend who also logs in as admin that he found an error message somewhere:
‘Warning: Division by zero in /home/rel24/domains/gaylinc.nl/public_html/wp-content/plugins/leaflet-maps-marker/leaflet-list-markers.php on line 44’
I don’t know how to fix this…..
