The main site does not have period and level. So it may throw a fatal error. Please update the code a bit from line #94 to #98.

$period = empty( $blog_info->term ) ? '' : $blog_info->term;
$amount = empty( $blog_info->amount ) ? '' : $blog_info->amount;
$timestamp = time();
$activation_key = empty( $blog_info->identifier ) ? '' : $blog_info->identifier;

or add is_main_site( $blog_id ) check before adding column data.
