After updating plugin to 0.9.6 thumbnails are not retina

It seems it works on a few pages but not everywhere. Might be caching, there was not breaking changes in the new version.

Can you try the client-method? That way you could make sure it’s not happening because of caching.

client-method not work (

retina 2x not happening only for thumbnails

The plugin is not loading on your page for some reason.

Server-side, right? Because I don’t see the file for the client-side loaded here.

Strange… I don’t see the script being loaded at all… I have no idea how to debug this at the moment.

Don’t you have any other WordPress install to try it?

This file https://danilkonovalov.ru/wp-content/uploads/2013/01/IMG_78541-225×150 has no retina equivalent (it should be https://danilkonovalov.ru/wp-content/uploads/2013/01/IMG_78541-225×[email protected]). Try to check why it is not being generated. Then post screenshot of your retina dashboard and settings.
