Something is broken….

I’ve been using this great little plugin for ages, and it’s always been perfect. But something has happened recently to disrupt it’s functioning and I’m not sure what’s up.

On the page noted here (https://nrocnetwork.org/resources/courses/nroc-math/nroc-math-standard/?target=instructors) there are many resources in the list with (secure) after the title. In each case, this should be replaced with a lock icon.

This is the way I have it in settings:

(secure) => <i class="fa fa-lock fa-lg"></i>

I haven’t made any changes (other than usual plugin updates). I’m running WP 4.9.8 and your plugin works fine on a test page (https://nrocnetwork.org/resources/test/). I suspect it must be something about how your plugin’s code is being parsed within the code generated by the WP Download Manager plugin that is generating the lists and the popup on the problematic page.

Can you tell what’s wrong, based on your knowledge of the plugin? Is there a way for me to fix this, or should I be talking to the other plugin author?

Thanks in advance.
