The preview works: Yes
It works with other themes: Haven't Tried - but was working until the latest upgrade
It works when I disable all other plugins: No - disabled all and same issue
Meta Slider version: Version 2.7.1
The Metaslider appears to claim the page and then for each new slide it fades out and then in again one whole height further down the page.
So it appears that if I have 10 slides that is takes up 10 x the normal height and then slowly image by image works its way through this reserved space.
