I've got Modals Pro ver. 14.2.3 installed and I've used modals with inline content with out any problems. When I try to load an article whether using the article name, alias or id the modal pop-up comes up with "This content failed to load".

I've followed the samples just changing the article attribute to match the article to test it out but cant' get it to load.
{modal article="My Article"}Link using article title{/modal}
{modal article="my-article"}Link using article alias{/modal}
{modal article="371"}Link using article id{/modal}

Can you suggest how I can to start troubleshooting this.

Thanks for your help
