Retina @2x images not found

What theme or plugin is responsible for enabling Retina compatible media? It’s illogical to need a Retina version of an SVG file *. Scalable Vector Graphics files are resolution independent. It’s kind of the entire point of using them. I recommend asking for help through the dedicated support channel of the module responsible.

* SVG files do have a “native” size, even though they can be scaled to any size. It’s conceivable that there’d be a Retina SVG file which has a double sized native resolution, but it’s entirely unnecessary.
