cant login dashboard admin

Hello!

I installed the plugin and configured all the fields

For security with another plugin I changed the entry address for site administration, it is no longer http://www.mysite.com/wp-admin now it’s http://www.mysite.com/newaddress

I configured with its plugin that users can not enter the address for the administrator

But now when I enter the address that I created for administrator (www.mysite.com/newaddress) redirects me to the page that is for others (users http://www.mysite / login) and I can no longer enter as administrator, even if I try to do it from That page tells me that my credentials are not correct.

Only entering via ftp can I access as administrator

Help me please
