Hi @ashley_c
Currently I can’t see Smart Slider 3 on your homepage. I can see you’re using Comet Cache – is it possible that you have not cleared its cache after you published the slider?
In any case, these kind of problems usually occur when the menu’s z-index is not high enough, not it’s not set at all.
The current, I think SiteOrigin, slider has the same issue, so I was able to check and possibly figure out the problem.
When your menu is not in “fixed” position, so when it’s at the top of the page, it has no z-index set. In fixed position, it has z-index:
nav.fixed {
top: 0;
z-index: 999;
left: 0;
right: 0;
transition: all 0.3s ease;
-webkit-transition: all 0.3s ease;
-moz-transition: all 0.3s ease;
}
coming from: /wp-content/themes/shapely/style.css
As this 999 z-index should be high enough, I suggest adding the same value to the not-fixed position:
.main-navigation {
position: relative;
z-index: 999;
}
you can put this code to Customizer > Additional CSS. This should fix the problem.
