When I tried to void a transaction (payments, invoice, etc) - by going to Setup > Maintenance > Void a transaction
I get an error message:
"The selected transaction was closed for edition and cannot be voided."
The transaction I am trying to void is from this year.
The current fiscal year is 1/1/2022-12/31/2022 and previous years have been closed.
It appears the problem is the current version is not compatible with PHP 8.0. When I switched the PHP back to 7.0 from 8.0, the problem went away, and I was able to void transactions without the error message. So there is a problem with compatibility with PHP 8.0
