Meta Box

Can confirm this too, at least for the admin area (seems, on the frontend it is working).

Text limit 100 characters is set in field group.
"Character Count: 50/100" is shown on a text fields.
BUT not on textarea fields.
So, more text is entered as allowed...
Will this be fixed?

YES - looks familiar 😉

YES can second this,
- deactivated all custom scripts (PHP, js, css)
- have disabled all add-ons
- deleted all field groups
- created a new field group and put some elements into that group (only standard values) updated/saved
- reloaded field group edit page
- (still) fields, which should exist as saved before, are not visible !!
- seeing the same console errors
So, if there are already two, it seems not to be on our side. (?)
Please let us know ASAP what happened...
Thanks.

BTW: The field group + fields itself should be saved, as I can export the code (see below).
So it seems only the GUI is not working as expected.
