 * Hi,
    my installation of WordPress is complaining about the usage of date_default_timezone_set()
   within the Booking Calendar WpDevArt Plugin. Looks like WordPress doesnt “allow”
   the use of this function since the last releases. Any chance to remove the usage
   date_default_timezone_set() from your plugin?
 * Regards,
 * Jan
