PHP Error in debug mode

I’ve enabled debug mode in wp-config.php and when the events calendar plugin is enabled, I’m getting the following notice.

Notice: Trying to get property of non-object in /home/nbchurch/public_html/wp-includes/class-wp-query.php on line 2904

Notice: Trying to get property of non-object in /home/nbchurch/public_html/wp-includes/class-wp-query.php on line 2910

Notice: Trying to get property of non-object in /home/nbchurch/public_html/wp-includes/class-wp-query.php on line 2919

I don’t have any updates to perform to wordpress or events calendar but referencing the lines in the file mentioned, this is what each says:

2904:

if ( !$post_status_obj->public && ! in_array( $status, $q_status ) ) {

2910:

if ( $post_status_obj->protected ) {

2919:

} elseif ( $post_status_obj->private ) {

The following is the entire section in the php file that it’s referencing. Since it’s referring to post statuses, I checked the status of each of the 10 events in the calendar and they’re all set to “published” so nothing weird there.

// If the post_status was specifically requested, let it pass through.
if ( !$post_status_obj->public && ! in_array( $status, $q_status ) ) {

if ( ! is_user_logged_in() ) {
// User must be logged in to view unpublished posts.
$this->posts = array();
} else {
if ( $post_status_obj->protected ) {
// User must have edit permissions on the draft to preview.
if ( ! current_user_can($edit_cap, $this->posts[0]->ID) ) {
$this->posts = array();
} else {
$this->is_preview = true;
if ( ‘future’ != $status )
$this->posts[0]->post_date = current_time(‘mysql’);
}
} elseif ( $post_status_obj->private ) {
if ( ! current_user_can($read_cap, $this->posts[0]->ID) )
$this->posts = array();
} else {
$this->posts = array();
}
}
}
