You know guys , one of my user just lost his password of my site .And then he tried the button "forgot password" in the top of the page . First, of course ,the reset-password mail was delivered to his mailbox.But the link code didn't work ,and 404 error appeared . And then after more than a hour or a day ,he tried the button "forgot password" again and again , no reset-password mail will be delivered and always the error "Reset code already sent. Please try again in 10 minutes." was thrown out . So guys,What's wrong with my reset-password ?
