If there is more than one event a day (and only then), I get a 404-error.
The reason : with a click on that particular day, the calender generates (e.g.) the following link: http://www.mydomain/2012-11-01/ but it should be: http://www.mydomain/index.php/2012-11-01/ . All my other pages (em and other) start with http://www.mydomain/index.php., because I prefer the SEO-friendly “postname” permalink-structure. What do I have to do to make the calender work perfect with the “post-name” permalink-structure?
