Answer 1

Given that both screen grabs indicate that one or more indexes are stale. Start with those.

Next delete these folders, /var/cache /var/session /var/full_page_cache (under the Magento root) You will need to login deleting /var/session

Disable any recently installed extensions or modifications.
