Embed problem

Hi there,
I’m using WP Facebook Embed plugin for facebook embeds and if the CSS part of Autoptimize is active it crashes my website.

Since I have deactivated the plugin, everything works fine again.
I was only using the html and the css part, I was afraid of the JS, but unfortunately is not working now.

Here is a post for example with a facebook event.

If I turn on Autoptimize with CSS I lost the design.
Thanks,
Balazs
