@my17560 - I've tried adding these three lines to:
- /conf/meta.html
- /lib/tpl/readthedokus/meta.html
- /lib/tpl/readthedokus/main.php
With all three, those lines never show up in the header. I've restarted the container and cleared the browser cache each time just to be sure.
@oymyo - I installed the fontface plugin, set it to use Google Fonts, set the first font name as "Lato" and the second font name as "Roboto+Slab" but that had no effect. It also doesn't look like the plugin would allow me to enable both Google Fonts and Font-Awesome.
Thank you both for the suggestions. I'll keep trying to hack my way around this. Let me know if you have any other thoughts.
