To fix this error you can just edit the file "/lib/constants.php" and replace "https://services.skaredcreations.com" with "https://www.skaredcreations.com" in the constant definitions COMBU_UPDATE and COMBU_UPDATER.

Even better, you can also completely disable the check for updates by editing the file "/admin/lib/includes/common_functions.php" and replace the content of both functions "checkUpgradeAvailable" and "checkUpgradeUpdaterAvailable" with the following, so it will not even make a call to our updater and your server will save traffic and resources usage:

function checkUpgradeAvailable() {
    return array(
        "version" => COMBU_VERSION,
        "release_notes" => "",
        "updater_version" => null,
        "sql" => array(),
        "files" => array(),
        "delete" => array(),
        "scripts" => array(),
        "beta" => FALSE,
        "upgrade_required" => FALSE
    );
}

function checkUpgradeUpdaterAvailable() {
    return array(
        "version" => UPDATER_VERSION,
        "release_notes" => "",
        "updater_version" => null,
        "sql" => array(),
        "files" => array(),
        "delete" => array(),
        "scripts" => array(),
        "beta" => FALSE,
        "upgrade_required" => FALSE
    );
}

there's nothing like this implemented at this moment.

If you want to try yourself then I could suggest to use a new property CustomData in the server-side class LeaderBoard_User (as TEXT field on the table) where you could store the json representation of a dictionary/hashtable for the custom data for each leaderboard score. Of course it's not exactly straight-forward as implementation, but if you are also familiar with PHP programming then it shouldn't be extremely hard to add this field and manage it both in the server webservice and in the client classes/calls (you can start looking at how it passes the "customData" in the other entities on client side for example in the User class, and how it uses and stores that in other webservices).

I'm developing a number of racing games and I'd like to give some extra information on the leaderboards for the vehicle used and manual or automatic transmission & add the options for players to download the replay or ghost of the other players. I can't find any official way to do this so wondered how I could perhaps go about adding it myself?

Thanks

The tables (and their fields) must be correctly named (for example "Account" and not "account"), if they're not (it may happen on Windows machine running MySql) then you need to enable the case-sensitive option on your new MySql server (lower_case_table_names=2 under the section in my.ini) as I described in the documentation here for MySql on Windows machines.
