Today I installed W3 total cache on my site http://www.fotocomefare.com.
After configuring it, I disabled the preview mode and tested it on 3 browsers.
On Chrome I didn't see any problem, but it was the browser I was logged into, so I think cahced pages were not being served.
Sadly in FF and IE, the slideshow was not rendered and I could see only the list. I think it could be related to js minification, but I didn't know which options to change, so I decided to disable W3TC.
Does someone have a suggestion on how to solve this?
