monkeybrain on "Theme update script breaks WP Availability Calendar & Booking"

Thanks Jan,

Yes, I figured as much. It probably is just a small detail somewhere in these 100 lines of code. But being more of a front-end guy I can't find the error.

Maybe someone else can have a look at it. Or maybe someone can tell me how much work it would be to fix it, I guess I could pay for an hour or so.

As far as I see it checks the theme version, pings the API and if there is a newer version it updates the theme. And I have no idea how any of that could break the plugins functionality.

Thankful for any suggestions.
