If you reinstall the latest version of DataBridge and reapply the recordset server behavior, then it should create a new rsobj.php that won't have the curly braces error. It looks like you would also have to re-apply your user authentication server behavior to get a new version of the authentication.php file.
If you attach the file: numeroset\home.php then I can take a look and see if I can spot the parameter mismatch error.
