For the last week or so I've been unable to use both the theme preview and customiser functions, as on both the page disappears from the screen completely after 1-2 seconds. Previously all was fine and the problem persists on three different computers; after caches and cookies have been cleared, and across all browser platforms.
Is it just me, and if it is can something be do resolve the problem?
many thanks,
Tony
