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 \_.” Litium version: 6 ---

Could there be a space in any of the names? ---

Just to double-check – no å, ä or ö either in the name? Would it be possible for you to share a screenshot of what you want to add? ---

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? ---

I think you got some corrupt data in DB, check the tables and see if any issues. ---
