wps-hide-login plugin

I decided to hide the standard URL for entering the admin panel. Installed the wps-hide-login plugin. He entered the desired ending and lay down. I try to enter in the morning. I enter my site / login123 and can’t get in. already tried everything. deleted the plugin folder. I was looking for where the entrance address is registered. if you forgot the login page that you created. or the plugin is stupid. help to return the standard login page. thanks
