Here's something to try (no guarantees)
In Extra CSS, change all the instances of
Code:
@font-face {font-family: "Georgia"; ...
to
Code:
@font-face {font-family: serif; ...
and change
Code:
body {font-family: "Georgia", serif; }
to
Code:
body {font-family: serif;}
leaving the only references to Georgia in the .ttf filenames.
