Hello. I was testing the last version of this great plugin, but I took a little disappointed to find that the plugin does not work with the system cache, because MJ is turning off my system cache plugin (although in plugin manager it seems turned on). I know this because all updates are showed instantly in frontpage

I am right? Or something is failing on my site?

Thanks in advance.

Buph, MJ disables SystemCache plugin for mobile devices only (so for desktop browsers it works). It's because MJ is able to generate different pages (i.e. markup and image sizes) for different devices, and SystemCache plugin fails in caching in such a situation.
