Book store envato theme

Hi,

I already asked for help on my theme’s forum but am desperate as they have not replied.

I recently updated the theme and wordpress and don’t know which is causing the problem, but the formatting is all wrong, running over each other on the mobile sites and such, and not displaying the slider and other such content on the actual website, even if on the wordpress page setup they are there.

Can anyone help?

Eternally grateful,
