Figured it out. Navigate to the following url: http://yourwordpresssite.com/wp-admin/plugin-editor.php?file=events-manager/em-events.php&a=te&scrollto=2467
The top two lines should look like this:
//add_filter ( ‘single_post_title’, ’em_content_page_title’,1,1 ); //Filter for the wp_title of page, can directly reference page title function
add_filter ( ‘wp_title’, ’em_content_page_title’,10,1 );
Change that second line to the following:
add_filter ( ‘the_title’, ’em_content_page_title’,10,1 );
Looks like Marvin was just using the wrong filter :-/
