Heads up! this post was created when Microthemer was at version 6. The current version is 7. Some references to the interface may be out of date.

Hey,

Thanks for reporting this. I just checked at my end, and didn’t get the same error ($args->menu is a valid object). Would you mind providing me with access to the site via our secure contact form so I can troubleshoot this further? If that’s a problem, I could send you an updated version of Microthemer that I think will handle this without generating an error, it just might involve a bit more toing and froing.

Cheers,
Sebastian
