Hello,
I have the same problem
Fatal error: Cannot redeclare tep_validate_password() (previously declared in C:\Inetpub\vhosts\XXXX\httpdocs\includes\functions\password_funcs.php:16) in C:\Inetpub\vhosts\unnecessary-necessity.com\httpdocs\includes\functions\password_funcs.php on line 29
... I tried to find the admin/includes/change_password.php but could not find it in the includes, there is no file called change_password.php i searched the whole FTP to this File.
So how can i fix this issue.....
