https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=28586 --- Comment #6 from David Nind <david@davidnind.com> --- Testing notes (koha-testing-docker): - To reproduce the issue: . Set a value for ClaimReturnedLostValue, for example: 4 . Check out an item to a patron . Go to the patron's check out page > show check outs . In the 'Return claims' column select 'Claim returned', enter a note and click 'Make claim" . Go to to the Claim(s) tab and select Actions > Resolve > select a resolution reason from the drop down list > Click on 'Resolve claim' . Select a reason and enter some text - Before the patch is applied the page just hangs and there is the [warn] message (see bug description) in /var/log/koha/kohadev/plack-error.log - After the patch is applied (and browser cache cleared) the browser no longer hangs and there is no warning message in the log -- You are receiving this mail because: You are watching all bug changes.
