CallPage & Revolution Slider

Hi, I have a WordPress website and I installed CallPage, but when I activate and configure the plugin my slider (revolution slider) only loads the first slide then freezes on the second one only loading the background.

Right now I have disabled the plugin the CallPage plugin and placed the code in the footer section as suggested as an alternative option, but end up with the same result.

I have spoken to the Support but they have not encountered this before and so also don’t have any possible solutions.

Any help will be appreciated!
