Hello! I am have been fiddling with your plugin, it is awesome. However, when trying to use the wp retina 2x plugin within a multisite; trouble starts to appear. Hopefully there is someone who has encountered the following issue and has found a solution.
First of; client side isnt an option as it doesn't allow my images to be responsive. So i tried the server side option, but without succes. Tried to update the retinaimages.php, added the rewrite rule, but no luck. So i finally chose the html rewrite.
Html rewrite works! BUT only when debug mode is enabled. The same goes for the client side option. It works, but only in debug mode.
This is happening on local, on a staging server ánd on our live server. So i don't think its a Cloudflare thing. Does anyone recognize this issue?
