Styles break when saving changes (also throws console errors)

Hi,

Every time I make a change and hit save after editing anything in BB the page styles break. If I refresh the page they all work again. I also get a raft of console errors on any page that loads BB even before I edit anything, as seen here http://i.imgur.com/dbhjYoM.png

If I disable the Better WordPress Minify plugin the styles stop breaking whenever I save, but the console errors are still always there. I can live with the console errors but is there a way round it so I don’t have to disable BWP? The client will need to edit the site using BB so I can’t really leave it turned off permanently just in case they want to use the builder.

Thanks
