Hello  👋

Can you please provide the following information:

  1. Are you trying to upgrade to Backdrop from a previous version of Backdrop, or from Drupal?
  2. What is the version of Drupal/Backdrop you are trying to upgrade from?
  3. What is the version of the Backup and Migrate module you are using?
  4. What is your version of php?
  5. If you open the settings.php file, what do the $database and $database_prefix lines look like?

@philippeg - Very important update. You must update the Backup & Migrate module immediately. The update to Backdrop 1.19 seems to have uncovered some hidden problem in Backup and Migrate module that has already been fixed and released. 

See: https://github.com/backdrop-contrib/backup_migrate/issues/63

This issue is causing this error and may be having other unintended side effects: 

Error : Call to undefined method DatabaseConnection_mysql::exec()

ha ok i thought it was only a matter of cache so not so simple; i migrated from previous version of backdrop.
