No, sorry, that’s not the problem, the code is generated, but the fields I add with register_field_group never show up (either front or back-end). I was responding to your link. The issue in that link looked like it was when register_field_group was included in a theme file, I was just saying that I call register_field_group in a plugin.
I’ll try to test the most updated code from git-hub today if I get a chance.
