Error when deleting/updating field

[Alpine418]

Hi,

I got the following message when I update oder delete an text field:

The update works. But deleting the field does not work. All other fields doesn't have any problem.

How can I hard-delete the field in the db? Or is there any other solution?

Thanks.

This solution does not work. Same error occurs.

Was a problem with the AutoTemplateSubs module. After I uninstalled the module, the error did not occur anymore.
