My Debut Drop down Menu not working

Hello, i had a drop menu set up for now two years. It was perfectly working until few weeks ago.
I’ve tried to re-set up it but still nothing.
I’ve also found out that, on me mobile interface the menu icon (three bars) is not working at all as well.

Can you help me ?
I’ve tried looking similar solved issues on the discussion but nothing worked out.

here’s the URL of my website : https://lechapeaumagique.com/

Thank you very much !

Hi @Nath_ida

It Seems there are some jQuery-related errors in your console try to resolve that sometimes the jQuery of the whole store won’t work if there is an error otherwise you can try adding a class for mobile using jQuery on click that will help.
