Recently, WorldPay changed the way they accept connections. This caused some difficulty for users of WebStore-WorldPay. Brian was able to discover the solution and sent it in.

All you have to do is find the following line in cgi-lib.pl

if (!defined $meth || $meth eq '' || $meth eq 'GET' || $type eq 
'application/x-www-form-urlencoded')

and change it to:

if (!defined $meth || $meth eq '' || $meth eq 'GET' || $type=~ 
/application\/x-www-form-urlencoded/)
