This is due to your server being configured to use memcache, but memcache is not compatible with php 7.3
You should talk to your hosting provider about this.
Thank you.
The provider told me that as well as upgrading (through my cpanel) I need to edit the php.ini file to version 7.3
That certainly caused the warning message to disappear and hopefully everything is now working OK… though yet to check.
