WordPress 6.4 Multisite – Page Updates – CONNECTION LOST

Have upgraded to WordPress 6.4 earlier today. When trying to update pages am getting a ‘connection lost’ error – this also seems to cause website to become very slow for a period.

Have tried increasing php memory limit, – using PHP 8.2.

Anyone with ideas on how to resolve / patch please. Have full back up so can revert to 6.3 if all else fails.

Thank you..
