Undefined is not an object (evaluating 'e._tag')

[mactedder]

I keep getting this message popping up in te panel when changing content. What does it mean?

The error message indicates that the system is trying to access a property or method of an object that is not defined (that is, “undefined”). In this particular case, the code is trying to access the _tag property of an object e, but the object e does not exist or is not defined.

Thanks for feedback. This must be something withing the core files of Kirby then because I have not created something called this?

Have you checked your config.php for additional entries that may be related to missing files?
Maybe a plugin is the reason. You might find some useful information here:
