I developed this site and then realized I hadn't set it to https. We hadn't taken the site live or anything, so I went ahead and switched it on our server to https. Everything is working well after turning on the SSL except for the icon fonts. I did a search and replace for the file and I thought that'd fix it, but it hasn't. I tried purging caches. I'm at a loss of what to do. How can I get the icon fonts to show up correctly again?
Enabling SSL is falls basically to the same category as migrating a website to a new domain. To resolve the issue you can just regenerate the icons (and most likely also the theme) stylesheet as per Website migration instructions.
