>From the source code :
if (!wpa_s->conf->update_config) {
		wpa_printf(MSG_DEBUG, "CTRL_IFACE: SAVE_CONFIG - Not allowed "
			   "to update configuration (update_config=0)");
		return -1;
}

Maybe add update_config=1 in your configuration file.

The best way to find the reason is to launch wpa_supplicant in debug mode
