In the controlpanel in websites and in the sitetypes and templates, I’ve added some properties to the “CheckOut” sitetype but can’t update the field value. When I try to save I receive
“Ett fel inträffade”
“Namn måste anges för alla fält. Namnet får endast innehålla a-z, 0-9 eller _.”
Could it be another one of the old fields for some reason was successfully saved with invalid letters in the database. So now when you try to add a field, you get an error… but not for the new field, but for an old field?
