Updating my php fixed it for me thanks for your help Edward.
Thanks for your help, I’ll update my php & let you know if any further issues, did notice it was out of date some weeks ago
Thanks for the reply.
No, just opens a page saying “There has been a critical error on this website. Please check your site admin email inbox for instructions. Learn more about debugging in WordPress.
No email actually comes through. It only happens when I check the box to broadcast it & update. I use Broadcast quite regularly, and see there was an update a few days ago, am wondering whether its an issue there, or just a coincidence?
