Just unsuccessfully tried to upgrade from MV 4.02 to 4.03, hit the restore button but now my store is closed and I can't find the open store button. Other threads said there's a link on the bottom right (I assume they mean on the dashboard) but I can't see it.
Just checked one of their demo stores just in case I was mising soomething but no link on bottom right there either. The odd thing is I vaguely remember there being options down there.
Settings|General - Close Storefront checkbox
