Finally had artist create svg logos and images for the site. But Customizer > Site Identity won’t let me upload the site icon or logo as svg. I know you can use svg for this (I was sure until now), how do I make it work?
For security purposes, WP doesn’t allow to upload SVG files.
You can install a plugin like SVG support to safely upload your SVG to the media library, once the SVG is uploaded, you can either keep the plugin or delete the plugin.
