I'm working with de 2.1.4 Version and I'm having a problem with my Administration Control Panel.
When I click to Control Panel I get the page, but when I click some Item like Groups, User, Categories, ... I get the left menu, but on the right frame I get this error :
---- BEGIN ----------------
HTTP Status 404 - /admin/
