Hey @acuperfect

Thanks for reporting this to us.

The issue was caused by the count() function being called on a null value in the Update Overview widget for specific sites, resulting in a fatal error. We fixed it by adding a check to set the count to 0 if the value is null, ensuring compatibility.

The development team has prepared a pre-release version that includes this fix.
I’m sending it to you via a private message.
