Database problems

Hi,

I recently installed Jetpack and couple of days in I had DB problems and my site went blank.
Is this a known issue?

These were the messages I had when I attempted DB restore once with WPBackup and once with my hosting site backup:

SQL query:

—
— Table structure for table QvPEXAHsactionscheduler_actions
—

DROP TABLE IF EXISTS QvPEXAHsactionscheduler_actions
MySQL said: Documentation

#1046 – No database selected

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /homepages/20/d210258374/htdocs/clickandbuilds/SoccerCoaching/wp-content/plugins/wp-all-backup-plus/includes/admin/class-restore.php:107 Stack trace: #0 /homepages/20/d210258374/htdocs/clickandbuilds/SoccerCoaching/wp-content/plugins/wp-all-backup-plus/includes/admin/class-restore.php(67): Wpbp_Restore->restore_database(‘/homepages/20/d…’) #1 /homepages/20/d210258374/htdocs/clickandbuilds/SoccerCoaching/wp-content/plugins/wp-all-backup-plus/includes/admin/class-restore.php(48): Wpbp_Restore->restore_complete() #2 /homepages/20/d210258374/htdocs/clickandbuilds/SoccerCoaching/wp-content/plugins/wp-all-backup-plus/includes/admin/class-restore.php(38): Wpbp_Restore->restore() #3 /homepages/20/d210258374/htdocs/clickandbuilds/SoccerCoaching/wp-content/plugins/wp-all-backup-plus/includes/admin/class-admin-settings.php(114): Wpbp_Restore->start(1) #4 /homepages/20/d210258374/htdocs/clickandbuilds/SoccerCoaching/wp-includes/class-wp-hook.php(287): WPALLM in /homepages/20/d210258374/htdocs/clickandbuilds/SoccerCoaching/wp-content/plugins/wp-all-backup-plus/includes/admin/class-restore.php on line 107

I deactivated Jetpack and all was fine again.

Any thoughts, please?

Thank you
