Can't switch to different month

Hi!

I couldn’t figure this out by myself so here is the problem; The calendar won’t stop loading when trying to switch month (by using the links below the calendar). I believe it has something to do with my child theme because it works just fine when using the original contango-theme.

I would appreciate if there is something I can do to fix this. I already looked mine functions.php-file after trying to reinstall the plugin. Here is the page I’m talking about.
