Day View 500 Error

Need help with an issue where the code below was breaking the day view. My calendar has alot of events per day and it seemed that the code below was having issues with this. (Maybe due to $new_title coming back as an array).

In search console I had the following error:

“Failed to load resource: the server responded with a status of 500 (Internal Server Error)”

In my error log I had the following errors/warnings:

Here is the code I commented out and it started working again…

/**
final public function title_tag( $title, $sep = null ) {
// WP >= 4.4 has deprecated wp_title. This conditional (and the lower one) adds support for
// the new and improved wp_get_document_title method and subsequent document_title_parts filter
if ( ‘document_title_parts’ === current_filter() ) {
$sep = apply_filters( ‘document_title_separator’, ‘-‘ );
$the_title = $title[‘title’];
} else {
$the_title = $title;
}

$new_title = $this->get_title( $the_title, $sep );
$the_title = apply_filters( ‘tribe_events_title_tag’, $new_title, $the_title, $sep );

if ( ‘document_title_parts’ === current_filter() ) {
$title[‘title’] = $the_title;
return $title;
}

return $the_title;
}
*/

I tried deactivating all plugins and the issue still existed.
