Hi Rose,
We were able to figure out what is causing ALL these problems. Somehow Rev Slider was embedding into a specific menu item – see this link `http://test.olgalishansky.com/wp-content/uploads/2018/12/Screen-Shot-2018-12-17-at-11.37.46-AM.png
This is internal theme bug, which needs to be fixed. If you need steps to reproduce it, please let us know.
Sincerely,
