Instead of loading the homepage it loads saying "error you must log in or sign up to view your profile" in place of the home page article and modules. My suspicion was it had something to do with the community builder extension. Anyway, I have went to the extent of trying to delete/ uninstall the community builder extension and it still does this. It displays the community builder webpage/ browser title when it has this screen in place of what is supposed to be the homepage article.
