I’m having this same issue and it’s driving me absolutely nuts. Tried changing them to text fields, deleting and re-creating the options page, changing field labels/names – nothing works.
The thing is, every other field works and I can save the page just fine. It’s only when I input text into those trouble fields and hit update that it throws the error.
I can only guess it has to do with the text and/or url field in the options page.
Any help here would be much appreciated, Elliot. I’m fresh out of ideas. Thanks for all the hard work.
