You’ll need to make a change to
admin/shipworks3.php
to get ShipWorks working in Zen Cart 1.5.5. Remove their copy of the function
validatePassword()
and replace it with
function validatePassword($plain, $encrypted)
{
$zcPassword = zcPassword::getInstance(PHP_VERSION);
return $zcPassword->validatePassword($plain, $encrypted);
}
This issue has been reported to ShipWorks.
