I don’t see anything that stands out in the group that should keep it from working, and none of the field names are long enough to require this
– changed wp_options/option_name lenght to 256 (not sure i did it properly, see attached screenshot)
When you say the value cannot be modified, explain what happens.
You go to the editor to edit the post, you click you mouse into the field.
Can you change the value or is it disabled so that you cannot enter changes?
Is this something that happens when you try to update the post? Does it somehow fail to update and show the old values again?
Is this all fields or just some fields?
