Hi @James
But the free version can save the field values when I publish a post. Did U know the reason?
Hi, really not the length of options_name characters.the fields including a field group with 4 fields, and I modified the options_name column of 128 characters, but not work. But I really did not know why the free version work very well!
the debug mode did not show any error in post publish process. I only can wait for next update, now use the free version.
