domsonline Hi
1/ I assign that 'Push Notifications' menu item to 'Cassiopeia' - a standard template of Joomla and the same error happens.
This error appears in console tab of browser:
Refused to display 'https://dashboard.onesignal.com/' in a frame because it set 'X-Frame-Options' to 'deny'.
I suggest you to contact your hosting provider for help to check this 'X-Frame-Options'
2/ You can try to use this custom CSS:
@media (max-width: 576px){
.t4-main-body .sidebar-l {
order: -1 !important;
}
}
put into file: root/templates/ja_beauty/local/css/custom.css
3/ I'm afraid that this template doesn't have option for that bottom navigation, you can search for a 3rd party extension supporting this feature.
Regards
