Hi Donna,
You have this CSS in your site which is hiding the navigation and header:
media (max-width: 768px)
#site-navigation, .site-header {
display: none!important;
opacity: 0;
}
}
I’m not able to tell where it’s coming from, you could try to deactivate all plugins except GPP to eliminate the conflicts from other plugins, then activate them one be one to see which one is causing it.
For temporary solution, you could this CSS after you deactivate the mobile header.
@media (max-width: 768px) {
body #site-navigation, body .site-header {
display: block !important;
opacity: 1;
}
}
Let me know ๐
