Hi, I would like to report some strange behavior. It is a bit long story (feel free to skip to the last three paragraphs), but please tell me what you think about what is happening. Initially we were running Koha 3.22.08. Due to some unrelated reasons, we had to remove and reinstall koha. So we ran "koha-run-backups", and then did an apt-get --purge remove koha-common followed by installing the package again. Everything seemed smooth except the fact that the circulation history get's deleted when books are checked back in. Fearing that something has gone wrong, we did a koha-restore. But koha-restore always failed because the user 'myInstanceName-koha' already exists. I manually tried removing the user using userdel, but it could not be removed because some other processing was logged in as the same user. Even rebooting did not work, so I uninstalled koha, rebooted, deleted the user and then installed back koha. This time, koha-restore worked fine except for a lot of "ERROR: File exists ". Now the problem is that whenever I change any value in the global system preferences, it does not fully take effect. So it takes effect half the time when I reload the page, and half the times it does not. For example, if I allowed batch checkout to a category, it is allowed half the times I try to do a batch checkout, and half the time, it is denied. But rebooting the system results in the changes reflecting permanently. I am very concerned as to weather I have done something wrong. Please tell me what you think is happening. Or is this some new bug in koha that everyone is experiencing? Thanks!
