The calendar works fine with my published iCal ics file except the details stored in the NOTES area fail to be displayed completely. I'm adding URLs in the notes that link to Google Maps for events that are happening at various venues. The only data that is displayed is the text 'Map to event:', the URL should follow on the next line, but there is nothing. I have updated the iWebCal.php file to fix the issue with the JInputFilter to JFilterInput. That fixed the error about the class not existing. If someone can fix the problem I'm having with the notes, then this extension will ROCK!
