I am no longer able to access the sub-site dashboard. It returns a message: Safari can't open page. Too many redirects occurred trying to open "www.republicofplato.org/SanDiegoCA/wp-admin/". This might occur if you open a page that is redirected to open another page which then is redirected to open the original page.
If I try to access the sub-site directly it now shows what appears to look like a Site Map.
