I tested with a link but still this bug loading: /

 {
                        module: "calendar",
                        header: "Vacances",
                        position: "top_left",
                        config: {
                                calendars: [
                                        {
                                                symbol: "home",
                                                url: "http://www.education.gouv.fr/download.php?file=http://cache.media.education.gouv.fr/ics/Calendrier_Scolaire_Zone_B.ics"
                                        }
                                ]
                        }
                },

Hi all and thank you in advance for your help, currently I work on the MM² but I can not put my calendar google I put my calendar google open but nothing works. (Of course, before coming I go to see if there is any other topic of this kind with a solution but I have not seen anything that managed to fix my problem.) So here is the code if someone can come to me help.

 {
                        module: "calendar",
                        header: "Vacances",
                        position: "top_left",
                        config: {
                                maximumNumberOfDays: 14,
                                calendars: [
                                        {
                                                symbol: "home",
                                                url: "http://calendar.google.com/calendar/ical/alexandre.khefifderain%40gmail.com/private-a6e25e4ddddedc010eada6/basic.ics"
                                        }
                                ]
                        }
                },
