I'm using your great plugin for a Festival website; It has to be a multilanguage site so we used the WPML plugin with the "Events Manager and WPML Compatibility" module.
Everything seams to work fine except for the page that lists events by a category; for that we get a white page.
In the events settings - > page -> Event Categories panel we set the "Override with Formats" to YEAS; if we set it to "NO" than the page shows the events correctly but as Archive.
We try installing the plugins in a new WP instance to test if it was a problem of our configuration but we had no success.
If we turn off the WPML plugin than the page works fine showing the events of the chosen category.
Any suggestion would be really appreciated :-)
