Grid Format Crashes

I use this on a site that needs calendars in multiple formats, all coming from a Google calendar. The front page has a list of events and there is a calendar page with a grid. The front works perfect. The calendar page spins and then crashes. I finally just had to put back the Google embed on that page but wanted to let you know. Would love to have your prettier version on the page.
