Comment (by progmastery):

 Replying to [ticket:2732 progmastery]:
 This happens on homepage of the theme preview. Just go to theme page and
 click preview. If everything is ok, go back to the theme page and repeat
 the previous step until you occasionally see default theme preview.
 Browser chrome 57 windows, cookies enabled. There is no tab with other
 theme.
