Hi,

The function password_verify() is come from native PHP but only after version 5.5 as indicated here:
http://php.net/manual/en/function.password-verify.php

So you will need to upgrade PHP version server to enable this function, as well as another function password_hash().

Alternatively, you can change the source code from file "helpers/auth_helper.php" (from both frontend and backend sites) as below.

function hash_pw($plain_pw)
{
    // (optional) change logic here for different hash algorithm
    //return password_hash($plain_pw, PASSWORD_DEFAULT);
    return md5($plain_pw);
}

function verify_pw($plain_pw, $hashed_pw)
{
    // (optional) change logic here for different hash algorithm
    //return password_verify($plain_pw, $hashed_pw);
    return (md5($plain_pw)==$hashed_pw);
}

For sure md5 is not secure enough but this just shows an example about how you can change the hashing logic with your own code.
