Eliminate render-blocking JavaScript and CSS in above-the-fold content

Hi there,

I am using AccessPress Parallax your theme and i Love it thank you !

I’m just having an issue to have everything as wanted and it is under https://testmysite.withgoogle.com/ for best speed. I am just failing on
Eliminate render-blocking JavaScript and CSS in above-the-fold content

I fount a plugin that it suppose to help, but Scripts-To-Footer, but if i activate the main banner disappears, i assume it has some sort of conflict in between extension and js theme.

Is it any chance to let me know how can I do it?

thank you in advance ??
