Error: 2020 - Database not found
Problem
Upgrade SOMO and try to back up the old database
Solution
You need to back up the file manually.
Check the installation path:
/var/www/html/monitor
Search for any file that ends with .db
If you can't find any file, you don't have any existing database.
To continue with the upgrade, remove the folder /var/www/html/monitor
