have you download from here?
https://github.com/bitcrystal/bitcoinexchange-finalhere is all fixxed otherwise set error_reporting(0); in the config.php
its no important errors.
and here a little installation guide
in coins.php you change the names to add
$my_coins_names="Bitcoin,Bitcrystal,Karmacoin,BitQuark,Litecoin,Dogecoin";
For example to add the Freshcoin and remove the Bitcrystal i change that
$my_coins_names="Bitcoin,Freshcoin,Karmacoin,BitQuark,Litecoin,Dogecoin";
and in the my_coins folder you create the config php files for your coin.
For example I create a Freshcoin.php file in the my_coins directory with the following content.
<?php
require_once('my_coin.php');
$coin=new my_coin();
$coin->set_name("Freshcoin");
$coin->set_prefix("FRE");
$coin->set_fee(0.01);
$coin->set_feebee($coin->getName());
$coin->set_buy_fee(false);
$coin->set_sell_fee(false);
$coin->set_rpc_settings_coin("USERNAMERPC", "PASSWORTRPC", "127.0.0.1", "8330", "", 99999999);
?>
999999999 is the timeout for the wallet you can ignore this parameter
