We have an old installation (3.18.11), and have recently started seeing patrons who used to be listed as one category (Staff) all reverting to a different category (Student). We'll go in via admin and manually change them back, and then the next time we check them, it's reverted back to Student again. This is really messing up our stats and is also problematic because different categories have different borrowing privileges. Without a drastic update to the newest release of Koha (skipping many in between which I worry would cause a lot of problems), does anyone know if there were any bug fixes released for 3.18 that might fix this issue? Or is there some setting that might be causing this that we could tweak? I'm new to my position and to Koha, so I'm not sure how to remedy this issue. -- Sent from: http://koha.1045719.n5.nabble.com/Koha-general-f3047918.html
