no_posts_message not working as expected

I have a number of Display Posts lists that display search results to create lists of posts based on common topics. I wanted to have a message display when there are no posts in the search results. An example of this is:

`[display-posts no_posts_message=”Message here” include_content=”false” orderby=”title” order=”ASC” category=”Cat1,Cat2″ s=”gl”]

Instead, nothing shows up on the page. I had the issue when I first started working with the plugin and solved it by making the no_posts_message be the first argument, but this no longer helps.

Any advice would be greatly appreciated!
