Big problems after update with Slider and Contact-Formular

Hello Support-Team,

i have updated at Version ENFOLD 3.0.2.
I used WP Version 4.0.1. – all Plugins are updated and all was good.

But now is the Full-Picture-Slider on the start-screen not visible!!! and the Contactform is destroyed – all fields if you can fill up, not visible. This Problem only in the Frontend, if you look at Backend, looks all fine.

SLIDER
The startsite who installed the slider is correct installed and all settings are ok – BUT when you go into the frontend – you cannot see any Slider!!! What runs wrong?

CONTACT-FORM
The same game – in the backend all settings look good and all fields are installed – BUT when you go into the frontend – you cannot see any Form-Fields!!! What runs wrong?

SIDEBAR-PROBLEMS
The older problem with my own sidebar, is not yet fully solved. I have create a special sidebar for the shop-sites, all Child-Sites from the shopsite show what i want see – only the parent-site, this site shows a different sidebar, although the same sidebar from the child-sites is assigned – GRRRR i will crazy…

For a look – your Guest-Account from the last problem is active and can used it.

Please help me – i`m despair
