Hi
I just saw what was happening
I had:
/* poner separadores en menu*/
@media (min-width: 769px) {
.main-navigation .main-nav > ul > li:not(:last-child) {
position: relative;
}
.main-navigation .main-nav > ul > li:not(:last-child) > a:after {
content: "";
height: 20px;
width: 1px;
background: grey;
display: block;
position: absolute;
right: 0;
top: 50%;
margin-top: -10px; /* half of your height */
}
}
that I was using as menu separation.
I removed that CSS and now works fine.
So issue sorted.
Have a good day
