Drop down menu not working?

My drop down menu was working fine. I then downloaded a couple of new themes and previewed them. I didn’t like them, so I deleted them. Activello was my main theme the whole time. Now the drop down menu no longer drops down.

My website is: https://soniczest.com/

The drop down should appear when you click “Instrument” on the top left of the page.

Any thoughts would be gratefully appreciates?!

Hey there

I can clearly see the dropdown menu, it’s working without any problems for me: https://prnt.sc/vlb5c4
which browser are you using?

Thanks for looking into this!

My default browser is Firefox. It works fine in incognito/private mode, but doesn’t drop down when I’m in normal mode. It works fine in Safari. But doesn’t appear to be working in Internet Explorer.

Hi

Which version is IE?

Please try this css code and let me know results:

.main-navigation .menu > li:hover > ul {
opacity: 1;
transform: translate3d(0, 0px, 0);
-webkit-transform: translate3d(0, 0px, 0);
-moz-transform: translate3d(0, 0px, 0);
visibility: visible;
}
.main-navigation .menu>li>ul li:hover>a {
opacity: 1;
display:block;
}
