Increasing post limits

Please add posts_per_page parameter on get_all_post function.

For anyone still struggling, just edit index.php and change line 51 into something like this:

$options_pages_obj = get_posts( array(
	'posts_per_page'   => 100,
	'offset'           => 0,
	'category'         => '',
	'orderby'          => 'post_date',
	'order'            => 'DESC',
	'include'          => '',
	'exclude'          => '',
	'meta_key'         => '',
	'meta_value'       => '',
	'post_type'        => 'post',
	'post_mime_type'   => '',
	'post_parent'      => '',
	'post_status'      => 'publish',
	'suppress_filters' => true
) );

This way you’ll also get some other options, like category and sort order. For more info, see Template Tags/get posts.
