CMS Made Simple Forums

Pretty URLs work great.  No problems except one.  On both the news module and calendar module I sometimes still get "/index.php/" stuck in the URL.  This isn't a problem (beyond simple annoyance) in the news section because everything works, but the calendar breaks.

For instance, I go to /events-calendar/ and I click to check the next month and it sends me to: "/index.php/events-calendar/&m2year=2006&m2month=7", which spits out a 404.  Any ideas?

Ideally, I'd like to get rid of every instance of /index.php/...
