What is the name of the file where the function "sub change_password()" is implemented? If you say secure_lookup.txt that's good. But secure_lookup.txt is not a file provided with files on this page: http://jpdeni.com/dbman/Mods/secure_lookup.html.
secure_lookup.txt was a file used in older builds so some of it's parts like "sub change_password()" are still needed but implied for new builds? Thanks!
you also need to get one of the html files listed after the change password link
summary: if you want people to change their password you need to install IN ORDER:
