donven I have just checked on 3 diferent web browsers and the font shows a sans-serif.
Quite weird as the specific font family is reflecting fine in page source however, while debugging through web inspector, The font family from CSS file - /templates/gk_musicstate/css/normalize.css is applying:
html, button, input, select, textarea {
font-family: sans-serif;
}
and not the inline CSS rule-set which should come dynamically from Gavern Framework
To troubleshoot, Try disable 3rd party extensions one by one to check for conflicts as the similar functionality from Gavern framework works fine while replicating on local install
