I also have the Mobile Menu show up on the desktop. I have cleared browser caches and it is still there. I discovered I am using a child theme. I tried previewing the original catch box theme and do not like what that looks like on my site. (grandpickleball.org) I am quite new to this. (The developer has moved on.) I see the child theme is a style.css file of 3000+ lines which i am not eager to learn how to edit. For now, I would like to revert to the old catchbox theme. Do I recover the catch-box directory from backup and put it in place of the current catch-box directory to get back to the previous version?
