List disappeared

Hello,
I added a google calendar list under “upcoming events” on this page and it was working fine before. However the list is suddenly gone since last week and I can’t figure out why.
Would be grateful if i could get some help.

the short code that was working before but not now:

[gc_list_view start_date=”” end_date=”+1 months” date_format=”d F – ” orderbysort=”ascending” g_id=”8c2k92t9quon5tkt2dvchloahg@group.calendar.google.com” g_api_key=”AIzaSyAr_cYk4v0lJAbAOUdXjmLQeyJdIv9I7Pk” max_view=10 max_display=”” html_tag=”li” html_tag_class=”” id=”” hook_secret_key=”” lang=”” enable_view_category=”” g_id_1=”32696o2cog7e2tbgq7l90s48sg@group.calendar.google.com” g_api_key_1=”AIzaSyAr_cYk4v0lJAbAOUdXjmLQeyJdIv9I7Pk” g_id_2=”je538cm84dq4fp44v8emf80ktg@group.calendar.google.com” g_api_key_2=”AIzaSyAr_cYk4v0lJAbAOUdXjmLQeyJdIv9I7Pk”
