Broke WordPress Editorial Calendar plugin

Deactivating WP Optimize brings back the calendar. When I have it activated there is a white block over the entire calendar boxes except the days of the week bar. 🙁

I’d rather not get rid of either plugin. I use the WP Editorial Calendar daily and my site has been so much faster since adding WP Optimize.

So could you help a girl out? Thanks!
