Font Awesome 404 Error – no folder found

Jetpack doesn’t include fontawesome, or any /fonts/ folder.

The plugin includes 3 fonts, automatticons, the Jetpack logo font, and Genericons, but they’re included in the _inc folder in Jetpack:
https://plugins.svn.ww.wp.xz.cn/jetpack/tags/3.9.4/_inc/

I’d suggest that you deactivate and delete the Jetpack plugin, and install it again from scratch.

If you continue to experience issues, could you try to deactivate each one of your plugins, one at a time, and switch to one of the default themes like Twenty Fifteen for a few minutes, and let me know if you find a conflict with a specific theme or plugin?

Thanks!
