Social Login Problem

Hi, I’m using Better WP Security Plugin with the Hide Backend options enabled. I’ve always used a plugin to login with social networks credentials (Social Login Plugin), but when I started to use the Hide Backend options this plugin (and any other plugin with the same functionality) didn’t worked anymore. I’ve tried to edit plugin files in order to change login address from “wp-login.php” to “wp-login.php?[the_key]&” as suggested, but I couldn’t get the plugin back to work. I’ve also tried to edit those files and change login address from “wp-login.php” to my secret login slug, but the result didn’t change, the plugin is still not working.

What can I do to use this options and a social login plugin?

Thank you.
