double slash after URL showing in GA (404 page)

Site URL: https://thefavoriteco.com/

Hi all,

I have no idea what's going on. I suddenly see lots of direct traffic in GA going to this url: http://www.thefavoriteco.com// (I don't know where the extra slash is coming from in the URL or why there's so much traffic to it/ and time spent on page).

Has anyone had this issue?

I just found this post and maybe it's the same issue?

Thanks!
