Handmade: Titles break Featured Gallery widget layout

The following workaround will truncate the title at 30 characters.

Edit the slider-widget.php and replace line 52:

<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>  

with:

<h3><a href="<?php the_permalink(); ?>"><?php echo substr(the_title($before = '', $after = '...', FALSE), 0, 30); ?></a></h3>

Your final code should look like this:

                        <li>
                        <?php echo $image; ?>
         <h3><a href="<?php the_permalink(); ?>"><?php echo substr(the_title($before = '', $after = '...', FALSE), 0, 30); ?></a></h3>
</li>
