Revolution Slider stuck at loading
Reason for Revolution Slider failure found: the Rev Slider uses the hammer.js jQuery plugin. Elsewhere on my site I have installed the jQuery mMenu, which also has hammer.js among its scripts. I disabled hammer.js in mmenu, and the Rev Slider comes alive immediately. The clash centres around the event listeners functions in the hammer script. 

Haven't solved all though, mmenu still works fine but I do get a 'where is hammer.js' error thrown at me now of course. Will report when and how I solve that..
