https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=26300 --- Comment #11 from Charles Kelley <cmkelleymls@gmail.com> --- On our end the bug is exterminated. What caused the bug in the first place was that we used the wrong header in the OPACHiddenItems. Originally, we entered lost: [1, 2, 3, 4, 5, 9, 21, 22, 31, 32, 98, 99] Through other correspondence, we learned that the SQL column names were supposed to be used instead. So we got a copy of the column names from the Koha-community website and corrected the above bad entry to itemlost: [1, 2, 3, 4, 5, 9, 21, 22, 31, 32, 98, 99] The problem vanished. We got "lost" from what appears in some of the documentation, from a bit of intuition, and a bit of illogic. In summary, as long as the SQL column name is used, there isn't a problem. I suggest the documentation be amended to include such cautionary advice. -- You are receiving this mail because: You are watching all bug changes. You are the assignee for the bug.
