In order to get nRelate to work properly I have to tell W3TC to ignore minification of the nRelate JS. This works fine on the main domain, however, it still minifies for all of the sub sites thus breaking nRelate.
I have included each of the subsite urls in the ignore block, but it's not working. I've even tried forcing in the nrelate js in the footer, but it replaces that script with the minified version.
Is there a way around this?
