I’m uploading fonts via the Bricks custom fonts page. All of my fonts are loading via http and not https. Both of my WordPress addresses in General > Settings are set to https. I’ve also refreshed/saved my permalinks just to be sure.
Have you cleared your Cache?
Please remove the font files and add them again.
If this does not help: would you be so kind as to send temporary login credentials and a link to this thread to help@bricksbuilder.io using the email address you used during the purchase?
Assuming your SSL setup is correct, re-uploading the custom font should work and the URL should start with https://. If this is not the case, there is something wrong with your setup.
