I too am not able to create new patron categories. I have just finished installing Koha 3.16.00.000. I did this installation from source (koha-latest.tar.gz). During the Web-based configuration I got many mysterious errors saying something like “using passwords on the command line is dangerous”. Whatever. After logging in to the admin interface as the super user, I was instructed to create a patron. I tried to create a patron, but I could not because there were no categories. I tried to create a staff category, but my results were the same as the original posting to this thread: ...the newly created category just doesn't show up. I then tried to apply the patch, but my patch skills are limited. Patch kept complaining about hunks failing, etc. I then looked really hard at the patch and noticed the number of question marks was “diff”-erent: original: VALUES (?,?,?,?,?,?,?,?,?,?,?,?)" ); patch: VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?)" ); So I edited the source to add the questions mark. Still, newly created category just doesn't show up. What am I doing wrong? Can you send me the patch file as well as the patch command to use it? — Eric Lease Morgan
