Select Drop-down not working in 4.34

Hi JayPEG (like the name!)

I have them working fine on latest versions. Both the separate [month_year_dropdown] shortcode and the builtin with the large calendar

see
https://test.icalevents.com/large-box-calendar/largecalendar/
and
https://test.icalevents.com/agenda/musicbandagenda/

It did actually break briefly in 4.33 due to change away from $_REQUEST use (although wp says $_REQUEST should always hold $_GET and $_POST, on some people’s systems, it doesn’t. SO now the drop down uses $_GET for those sorts of things)

Perhaps you meant 4.33 not 4.34?

Please check on 4.35
