My themes always include the brilliant SETTINGS PAGE metaboxes (using tabs) and everything works like a charm, however, anytime I set up a new theme, for the first time I save the options, I get the following warning. Then, if I refresh the screen or simply save the options again, it never returns.
I believe it could be something on my code, but I have no idea what should I look for. Can you give me any guidance here?
Although I can live with it, I feel uncomfortable because it seems something is wrong behind the closed doors. =)
