Please update your church admin plugin to the latest version 0.5968 ASAP
Previous versions have created a plugin database backup in case of problems, with a message to download and delete it.
Someone kindly pointed out a number of sites where the backup hadn’t been deleted by the user. That means personal data can be downloaded by people who know where it is.
V0.5968 deletes the file if it exists and then recreates the backup with a very hard to guess filename.
It’s always worth downloading and then deleting the file, so no personal data is accessible.
