Enhance has a very good WordPress toolkit. It can update plugins, enable/disable plugins, change site URL, enable WP_DEBUG, manage administrators, reset passwords, etc.
You can manipulate PHP error log settings in Enhance but the easiest way to track down a WordPress error is to turn on WP_DEBUG_LOG in the WordPress toolkit. This will log to wp-content/debug.log.
If you install the backup role on a server within your cluster, your websites will also have backup/restore capability. There is also now the ability to back up to an S3 (or compatible) storage.
