Manu bar, Slider Banners, Latest post not clickable

Hi,
I’m back again????

According to Google, the website speed is too slow and I’m forced to install AMP and w3 total cache. Happily the speed is great but many interesting feature in the theme has been disabled.

The menu bar is not clickable, the slide bar is not showing, and some codes are showing under the footer
