When I try to load a google calendar per URL, an error message appears with the url without : and /. When I edit the iCalImport.php with my url set to $filename in the import function, I can import the calendar without an issue.
Something is removing the special characters from the given url.
Error:
Not a valid VCALENDAR data file: httpscalendar.google.comcalendarical86gpnrpb0opckmecs604b7kj0g40group.calendar.google.comprivate-d099a3ed458xxxxxxxxxxxxxxbasic.ics
