The editor toolbar field was blank. Even though a Default was specified, it was not working. So, I copied the lines of text from below "Default:" and "Each line contai..." and pasted them into the text field.
I repeated this for the "defaults" under available fonts list.
For me, the exact lines for "Editor toolbar" were:
...and for the "Default fonts"...
