1.5.1 upgrade glitch with random exhibit block


I've installed and upgraded to 1.5.1, but now I'm getting this error message:
Fatal error: Call to undefined function exhibit_builder_display_random_featured_exhibit() in ../themes/rhythm/index.php on line 8

The code in question is:

<div id="featured-exhibit" class="featured-box">
<?php echo exhibit_builder_display_random_featured_exhibit(); ?>
</div> <!-- end #featured-exhibit -->

Has this function been modified or moved somehow that's causing this?

Make sure that your Exhibit Builder plugin is activated.

It may be asking you to click an Upgrade button, since it was upgraded along with 1.5.1.

Oh, of course. That's completely fixed it.

Thanks, John.
