Hello Rose,
thank you for all your answers.
Related to the font-family question I found out that I just need to select the font again(in Revolution Slider) and it worked it seems that the GoogleFonts just need to be cached locally in RevolutionSlider.
Can you please provide us with an API key for the Screets Live Chat?
Related to the Visual Composer update we have the latest Version installed. Do you think this issue will be fixed in the close future?
Thanks & best regards
