Admin login redirects wrong

My site does not redirect to /wp-admin/ properly anymore??

Hovering my Login Button shows a redirect to /wp-login.php/wp-login.php and when I try to login the page redirects to /wp-login.php/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/wp-admin/

It end in an infinitive loop end browser ends this. But when I go back to my site I find that the login did work because I can go into the Site Admin??!!

Can someone please tell me how to fix this login or where or what to look for?

I tried re-uploading the wp-login.php and wp-settings but nothing changes :'(
