Description

There are several cases where xmlrpc is still accessing the config directly. This causes errors in PHP8 when the secondary has an empty, but existing tag.

The case below is when attempting to sync Virtual IPs to a secondary that doesn't have any Virtual IPs, but has a "<virtualip>" tag.

PHP ERROR: Type: 1, File: /usr/local/www/xmlrpc.php, Line: 399, Message: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/xmlrpc.php:399

If no VIP is defined on the primary, after any XMLRPC action, it will create an empty <virtualip></virtualip> tag on the secondary, and the PHP error will appear.

If there are no <virtualip></virtualip> tags on the primary and secondary and the Virtual IPs checkbox is unchecked under Select options to sync under System/High Availability Sync on primary, the empty <virtualip></virtualip> will not be created on the secondary after XMLRPC actions. And PHP error won't appear.
