reset password on website

Reset password submits but doesnt send the email to subscriber with new password, this was working up until recently when the website was reinstalled on the server. If the user is a subscribed member, but has forgotten password the the website has a feature built in that allows the user to enter email address, click submit, and an automated email will be generated and emailed to the user with a new password. I need someone to go into the website and edit the code that relate to the feature of reset password, this should only have something to do with the php and not the mysql database so should be perfect for someone who is skilled in php only.\r\n\r\nPlease let me know any questions you have and I will send the url and and give you user name and password once someone that feels confident in the job feels confident.\r\n\r\nThank you in advance.\r\n\r\n
