Saw a post with this issue - but I never saw any resolution. Installed Them Builder to test it out in a dev environment. Starting playing and created a theme trying some of the options. When I saved the theme - I no longer have the links or menus at the top of the page - or anywhere for that matter - to edit, access space admin, anything. So I am now stuck with a remplate with no controls.
How can I now get back in to the space admin section to reset my theme?
