hello,
after creating a backup with
# cp -a /var/lib/fail2ban/fail2ban.sqlite3{,.bkp}
the .sqlite3 file should be removed with
# rm /var/lib/fail2ban/fail2ban.sqlite3
to resolve the issue. if the file remains, the issue will remian, after reinstallation of file2ban by plesk installer.
best regards,
andy
