Seems like all the sites I’ve upgraded to 6.4.3 lose their icons.
In cornerstone in the inspector on each page the icons are defaulting to SVG’s.
The issue is with the change the theme options doesn’t default to SVG’s. As a result all icons across the site disappear.
I need to manually update the setting in the theme options.
I guess either the site shouldn’t default to SVG’s or the site should turn the SVG’s on in the theme options.
