Don’t work pop-up gallary after update

Hi!
Our gallery (version 1.9.8), after last update, stoped to work correctly. Gallery created earlier pop up is not working. By click on image, it opens an image attachment page. When we create a new gallary we cannot choose and apply any theme style. Can you help us?
