Hi,
So you mean that even with the "Support" user account, and going through the /index.php/tienda/user/cpanel URL you still have the "your-profile" alias in the URL instead of "perfil" alias like I do ?
Then I don't know what to do so that you can get the correct link like me.
Could you try disabling the "your profile" menu item via the Joomla menu manager and see if it goes through the "perfil" menu item ?
Also, I would recommend you to change the "access" of the "perfil" menu item to "public". That might help with the issue too. And anyways, if a non logged in user tries to access that menu item, he will be redirected to the login form, so no need to set access levels to handle that.
Personnally, I would actually recommend that you change the way you configured your menu items.
I would recommend that you delete that "acceder" menu item and that you change the "access level" of the "perfil y pedidos" menu item to "public". That way, the users will try to access the user control panel via that menu item, which will redirect them to the login form if they are not logged in, and then redirect them back to the user control panel after their login.
Right now, after they use the "acceder" menu item, they get the login lorm, but after logging in, they get an error message because the "acceder" menu item is not available anymore to them and they have to search for the "perfil y pedidos" menu item, so it's not user friendly.
