Hi,
Thanks for the interest in our plugins. I can answer your questions.
We do not have a list of known conflicts for the plugin and no information about WP-Directory.
We can try to help resolve the conflict, but not in the Pre-Sales Forum.
Here on the pre-sales forum, I’m afraid we do not provide technical support. I would ask that you take any technical support questions across to our wordpress.org forum – our staff scan it periodically and other community members may also be able to help out.
The Events Calendar
Also, two resources to look at can be our testing for conflicts guide:
Testing Conflicts With Themes and Other Plugins
And you might try this plugin to disable another plugin on the event pages to see if that helps:
Try using the Plugin Logic to disable other plugins on the event views and single templates:

Thanks again!
