Thanks for your response, Marcus!
I still have one issue to solve.
I want the <PubDate> tag to be the same as the events start date/time. I have the code I used to do this in v.2, but when I now edit /wp-content/plugins/events-manager/em-rss.php, the RSS feed does not change.
Should I edit an other file?
Or where comes the output from /wp-content/plugins/events-manager/em-rss.php ?
