I was tweaking the font styles in the Squarespace control panel and noticed that when I selected Typekit fonts they were falling back to the system default Serif font.
Step 1: Check whether the problem is with the domain name
When the Kit was created at Typekit’s website it was registered with koumparos.ca but not the underlying Squarespace name, so when changing the site it is not pulling the Typekit fonts.
Step 2: Add squarespace name to Kit
Go to Typekit.com, log in, select Typekit Editor then Kit Settings.
Add squarespace name to list of domains, and then save.
Wait a few* moments for the changes to propagate.
* Where ‘few’ is defined as ‘more than an impatient person would like’.
