No access to site after uploading a new theme (lots of warnings)

Hi guys,

Here are some further details:

The old theme was Salient and the new theme I uploaded was Shopkeeper. I did not delete Salient. I guess I uploaded an incomplete zip file of Shopkeeper. Now I can not even enter my Dashboard. (I am not an advanced developer at all). What to do?!

Every help is welcome! I hope we can figure this out…
