Hello, ORLA!
Thank you for noticing that.
Unfortunately, it seems you have found a bug in the theme.
Until we fix that, you can use the following code as a temporary solution (insert it into Customizing->General->Additional CSS):
/*Top menu visibility fix */
@media screen and (max-width: 992px){
#top-bar-wrap{
display: block!important;
}
}
Also, I found that you have too long Site title and it overlaps the mobile hamburger menu…
If you want to try to fix that, insert additionally the following codes at the same place:
@media screen and (max-width: 992px){
#agama-logo{
max-width: 70%!important;
}
.mobile-menu-icons {
max-width: 20%!important;
}
.mobile-menu-icons > div {
margin-right: 10px!important;
}
.mobile-menu-toggle{
padding:0px!important;
}
#masthead .site-title a {
font-size:5vw!important;
line-height: 50px
}
}
Regards
