Hey Josue,
thanks for your reply. Ahead of my first post I tried already the following change – without success:

avia.js:252
I changed:
$.fn.avia_scrollspy.defaults = {
offset: (parseInt($(‘.html_header_sticky #main’).data(‘scroll-offset’), 10)) + ($(“.html_header_sticky #header_main_alternate”).outerHeight()) + ($(“.html_header_sticky #header_meta”).outerHeight()) + 1 + parseInt($(‘html’).css(‘margin-top’),10),
applyClass: ‘current-menu-item’
}

to:

$.fn.avia_scrollspy.defaults = {
offset: 50,
applyClass: ‘current-menu-item’
}

The offset value is still 10.

Any suggestions?

Thanks
Ole
