I have tried to log in to my Theme's customize section. I notice there is a new button in the top menu, but the page reverts too rapidly for me to see what it is. Then I get a static page with no links, options, or exit. I simply have to quit and try again. I have done this about 10 times with no change. Something new has happened since I last logged in to customize (about 2 weeks ago) and I cannot find out what that is. As a result, I cannot change my slide show or add new pages. In fact, I cannot even work on the functions of my store.
