Hi Peter, sorry, I am out of ideas then. What you see seems to be related to *Bug 19457* <https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=19457> - If CheckPrevCheckout is set to "Do", then checkouts are blocked at the SIPServer (Needs Signoff] Turning the feature off should still have worked I think.

Dear Katrin,

Thanks for your information.

I was told that the SIP server was restarted for configuration changes to take effect frequently.

Thanks and regards,

Hi Peter,

that sounds right. Sometimes it takes a SIP server restart for configuration changes to take effect. That's what I'd try next.
