I am experiencing a performance issue that I believe is due to a missing file being called by my site. I am using the Sydney theme. The missing file is https://file.myfontastic.com/qT3KkfvicnPf5ZiWi4ZWMZ/icons.css
In the attached waterfall diagram, you will see that it is causing a performance issue.
You can view my site’s source code here (line 742 has the call to the missing file).
Please advise. Thanks.
