It would be nice if the warning to renew the patron record stood out a bit more and maybe even said something like 'Review the patron's information'
Created attachment 9709 [details] Patron expiration message Is this the message you mean? I've never had a complaint about this one. Is the problem that checkout is blocked an librarians don't know why?
I'm marking this "wontfix" since it seems to be working for most people. If I misunderstand what this is about please reopen and provide more details.
