about registrar_sync error

[rahulkg]

we are using a centralnic domain registrar. Though the sync functions like updation of next due date takes well , we get errors like  Sync Not Supported by Registrar Module when whmcs cron is run. And when checking with whmcs support and centralnic support, it was found that centralnic uses a php file centralnic_sync.php for syncing operation instead of registrarname_Sync() that is recmmended by whmcs and used by other registrars. So when whmcs calls centralnic_Sync(), the cron creates  above errors , so to avoid such error , is it ok, just to write function centralnic_Sync()  {}  without any  procedures in it.  And as the php file used by centralnic module includes so many pages , I think its not a good idea to put them all in the centralnic_Sync()  {} . Can you suggest a way to get rid of these errors?
