Google Fonts list from Typography tab is empty
Well, this might happen. Please make sure you get your own Google Fonts API key.
Once you get it, please add it into theTypography tab of the Theme options panel. Once you have it set and saved, please click the Flush transient button the same page.
What happens is that the API key we set by default in the theme is used by most of our clients, but Google has some limitations for each key. Once a number of requests is achieved, it might not get the Google Fonts list any more. To make sure you don’t get this issue any more, we recommend getting your own Google Fonts API Key.
