recovery of draft post (saved) appears lost footer and share icons

I’ve a few issues I’m trying to deal with. I’ve advantage theme.

I’ve a footer problem as it wont appear, I’ve done the changes as instructed. is there a switch on /off some where which i may have activated.

I have share buttons not appearing when accessing site from my computer yet apearing when accessing from my iphone, whats up?

now and this is most destressing I made a long draft post using page builder saved all the way but now all the data has disappeared. Ive tried to find it via screen ption/revision but no revision tab is present. The data must be somewhere. Can you give me a pointer? Thanks heaps ?
