im trying to connect my website to my wallet via php based rpc commands. Any altcoin i connect to works just fine, using a file setting the rpc variables...

$rpc_host = '127.0.0.1';
$rpc_user = 'myuser';
$rpc_pass = 'mypass';
$rpc_port = '10013';

im using just a basic jsonRPCClient

    }
}
?>

and my config file (e.g., bitcoin.conf) contains the following

server=1
daemon=1
rpcbind=127.0.0.1:10013
rpcuser=user
rpcpassword=pass

rpcallowip=127.0.0.1
listen=1
rpctimeout=20

running a simple getbalance command

if ($row['name'] == 'BTC') {
                             $bitcoind = new Client($rpc_user, $rpc_pass, $rpc_host, $rpc_port);
                             $lbalance = $bitcoind->getbalance($user_session);
                         }

and my getbalance function

function getBalance($user_session)
    {
        return $this->jsonrpc->getbalance("zelles(" . $user_session . ")", 6);
        //return 21;
    }

returns:

Warning: fopen(http://...@127.0.0.1:9332/): failed to open stream: HTTP request failed! HTTP/1.0 500 Internal Server Error in C:\xampp\htdocs\beehive\jsonRPCClient.php on line 133

Not really sure whats going on here?... works for all other coins. (doge, ravencoin, etc...)

Thanks in advance!!!
