Hello @esthervoorpubliek-nl,

The menu has overlapped because of your image height which is small.

However, we will provide the quick fix. For this go to Admin Panel > Appearance > Customize > Additional CSS and paste below given CSS.

@media only screen and (max-width: 1300px){
	#main-slider .cycle-caption {
		left: 45px;
		max-width: 100%;
	}
	#main-slider .cycle-caption{
		bottom:3%;
	}
}

You can even place the image with bigger height as well.

Hope this helps.

Best Regards!!
