Hello
Have you specified the correct cookie settings when installing? the settings table entries number 171-173 are where we store the cookie variables
However I think your issue is this
$md5dbpass = md5($dbpassword . $Globals['vblicense']);
More than likely in the photopost config-inc.php file the $vblicense variable has not been set correctly as that is needed for authorization and cookies to be set right. You can find your true license number at the top of your
vb config file as well as most other
vb files.
