Using the Saleforce SforcePartnerClient, getting this error when I try to query a custom object.  I am using the associated partner wsdl xml file for the account.

Error:

Unexpected exception of type [SoapFault] with message [Element {}item invalid at this location] in [/Applications/XAMPP/xamppfiles/htdocs/xampp/libraries/sforce/SforceBaseClient.php line 782]

Thanks,
