Hi Jenny,
That’s definitely possible 🙂
Please review the Themer’s Guide first of all, which covers the basics for safely overriding and customizing our default templates. In this specific case, you’d be interested in the following template:
pro/widgets/modules/single-event.php
Within your custom copy of this template, simply find this line:
<a href="<?php echo esc_url( tribe_get_event_link() ); ?>" rel="bookmark"><?php the_title(); ?></a>
Modify it so it looks like this:
<?php the_title(); ?>
Does that work for you?
