I’m having problems with the drop down menu as well.
The menu was working fine.
I then upgraded the wordpress, and did some content update.
then I found that the menu is not working.
I deactivated all the plugins. No difference.
the menu works fine with the Twenty Ten theme.
but when I switch back to my own theme, it still does not work.
The website is https://www.sanxia.org.uk/
can anyone help me identify the problem?
Thanks
