Thanks, Rikard,
The theme is now updated.

Revolution Slider is still not visible, I checked the forums and found a solution that works for layer slider and possibly Rev Slider too, but can’t test the solution as the file has been removed. Please see.

Could you please replace /enfold/js/avia-snippet-cookieconsent.js file with this one – https://github.com/KriesiMedia/enfold-library/blob/master/temp_fixes/Enfold_4_6_3/avia-snippet-cookieconsent.js and flush browser cache?

Thanks again for your help,
Tina ;-)
