I am using Events->Settings->Formats/Layouts->Events format to control the listing for the http://www.webiforum.com/en/webinars/ page. It is using the default events page just renamed. The top of the Webinars page says: This page corresponds to Events Manager events page. Its content will be overriden by Events Manager, although if you include the word CONTENTS (exactly in capitals) and surround it with other text, only CONTENTS will be overwritten. If you want to change the way your events look, go to the settings page.
The layout on that page is working just fine. The pages using the scope attribute are not reading the Formats/Layouts code. I am using [events_list scope="future"] and [events_list scope="past"] and they are both showing the original layout instead of the layout I did with significant changes.
