pages missing / video appeared behind slider revolution

Hello,

Recently I have tried to change hosting companies (not sure if this has something to do with the missing pages or not) and now I am missing two pages on my wordpress site as well as all the information that was on the home page – except the slider which now has a random video behind the slider.

I have gone through to check that everything is published and yes everything looks fine I cannot see any errors (I don’t know code so please be kind to me).
I also updated visual composer to now baker? I don’t know if that has anything to do with it either.

I would be really appreciative if someone could point me in the right direction.

Thankyou
