Font plugin hides all of Visual editor section

After installing Font Plugin, I opened a recently published post.
I could not see any of my text and the Tiny MCE options were gone.
Images also do not display.
Only the most basic edit options were at the top.
I could click on the HTML tab and see text and HTML markup, but the Visual tab did not display.
Upon refreshing the page, even the HTML tab option disappeared and the first option on the page was the excerpt field.

Using Atahualpa latest release.
