https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=40065 --- Comment #7 from David Nind <david@davidnind.com> --- For what it is worth (and I don't know the answer to why this is happening), testing on the current main using koha-testing-docker: 1. I created these patrons in the 'Patron' category (no other data added, apart from adding a card number): 1.1 Surname = Остапенко 1.2 Surname = Остапенко Firstname = Эвелина 1.3 Surname = Шимко Firstname = Остап 1.4 Surname = Сычев Firstname = Игорь Алексеевич 1.5 Surname = Сычева Firstname = Анастасия Андреевна 2. The DefaultPatronSearchFields system preference is set to the default: "firstname|preferred_name|middle_name|surname|othernames|cardnumber|userid" 3. If I do the first search in the description comment, I get a 500 server error in a pop-up window and a "Processing..." message. Search result, using the search in the sidebar with Search field = as per search, Search type = Starts with, Category =Any, Library = Any): Search: - Search: Остапенко - Search field: Standard Result - pop-up message: Something went wrong when loading the table. 500: Internal Server Error. Expected integer - got boolean. Expected integer - got boolean. Browser developer tools console error: Got 500 (Internal Server Error) DataTables warning: table id=memberresultst - Ajax error.
