Plug in not allowing font change

Hi, I’ve used this plug in for years and love it! However, right now it is not letting fonts be changed. Not even to the built in fonts. I disabled all plug ins to make sure the problem wasn’t a css code and once doing so the fonts were back to being changeable. Use Any Font was the first plug in I enabled back on and the fonts didn’t change anymore.

Any help here appreciated
