@richard, it doesn’t work, I think I don’t explain very well. I mean the wp-login page of the wp-admin is breaking and I even taught the error was from some certain plugin such as login lockdown but after I deactivated the plugin, I still experienced the same thing. So, if you have any help for this. I mean what can I do to make the admin login page to accept one-time login since the details are correctly entered into the box.
