There is a bug in OpenCart 184.108.40.206 in the password reset using forgotten password. This is an ocmod fix for that issue.
To install this in your opencart 220.127.116.11, download and extract the content, you will find a file with .ocmod.xml extension. Go to Admin : Extension > Extension Installer , and upload this xml file. Then Go to modifications and refresh. Now your password reset will be working properly.
