Done a manual upgrade of the plug-in.
That has sorted it.
No further action needed.
I’ve deleted the plug-in but it keeps returning me to the same message at
URL/wp-admin/update.php?action=upgrade-plugin&plugin=si-contact-form%2Fsi-contact-form.php&_wpnonce=aa02f913af
Welcome any thoughts

Developer confirms a fix: website
There’s a clash I get with the Latest Posts widget.
Taking that off makes the cslendar run fine.
