Menu bar vs. Widget
If you have a navigation menu with submenus in your header and a testimonials widget in slideshow mode at the top of a sidebar, at some point they may overlap and the submenu loses.
The remedy is to add this to your theme’s stylesheet or custom CSS function, or with a plugin like Simple CSS:
.wpmtst-widget { opacity: .99; }
Then your submenu and widget should play nice together.
