No, that’s not the reason. I dis-activated all plugins and it is still NOT working.
Also, it was working fine with FREE Evolve theme. Same plugins – 100% the same!!
I still have Free version in my theme (in-active) and if I activate it – Revolution slider works fine!!!
see the attached image. I just created it!
You can login to my dashboard and try to activate a FREE Evolve theme to see that slider will work immediately!!
