Excel export solution

If you get the error “Warning: “continue” targeting switch is equivalent to “break”. Did you mean to use “continue 2″? in […some_path..]/wp-content/plugins/advanced-cf7-db/admin/class/PHPExcel/Shared/OLE.php on line 290”

The solution is there. Open the file OLE.php, go to the line 290, change continue to continue 2, save the file and it fixed, works for me.
