Today I found out that the related posts are not shown in my site (e.g. http://www.fotocomefare.com/monitor-per-fotografia/, at the end of the post).
Inspecting the HTML, I can see that the div for nRelate is present, but it contains jQuery code and not the HTML with the posts.
I use w3tc but minify is now disabled. Also, if I enable minification I manually specify the files to minify, excluding nrelate js and css.
What could it be?
