[Plugin: Simple Real Estate Pack] Yelp not working in categories

Usually, excerpts are stripped off of any extensive HTML coding and other stuff (comparing to full post) and I suspect that it applies to shortcodes as well. I would recommend to add page breaks before the API shortcodes, otherwise that will result in slow page loads and too many queries to the API providers. Finally you’ll run out of your request allowance per day.

On the other hand, this could be also a theme limitation. To activate shortcodes in excerpts, try inserting this into your theme’s function.php file:
add_filter('the_excerpt', 'do_shortcode');

Great tip. I’ll try that. Thanks!
