Hey Alexander,
We appreciate you choosing PRO and welcome to the premium forums! I just did a quick test of the snippet from our ‘Add Next/Previous links to empty months’ Knowledgebase article on my version of Divi (2.7.5) and it worked fine for me. (see screenshot below)

Try adding the following code to the bottom of your theme’s functions.php file and visit your month view to see if it works properly. Let me know how it goes and thanks again for choosing PRO!
/**
* Allows visitors to page forward/backwards in any direction within month view
* an "infinite" number of times (ie, outwith the populated range of months).
*/
if ( class_exists( 'Tribe__Events__Main' ) ) {
class ContinualMonthViewPagination {
public function __construct() {
add_filter( 'tribe_events_the_next_month_link', array( $this, 'next_month' ) );
add_filter( 'tribe_events_the_previous_month_link', array( $this, 'previous_month' ) );
}
public function next_month() {
$url = tribe_get_next_month_link();
$text = tribe_get_next_month_text();
$date = Tribe__Events__Main::instance()->nextMonth( tribe_get_month_view_date() );
return '' . $text . ' <span>»</span>';
}
public function previous_month() {
$url = tribe_get_previous_month_link();
$text = tribe_get_previous_month_text();
$date = Tribe__Events__Main::instance()->previousMonth( tribe_get_month_view_date() );
return '<span>«</span> ' . $text . ' ';
}
}
