Hello,
I think that the issue you describe is probably due to the (updated) theme or maybe another plugin(?) handling page scrolling on your menu links.
I checked your menu links with browser’s dev tools and they seem to have an additional js click event (I don’t know if this was the case with your theme’s previous version or if this is a new feature).
I run some tests in the browser with the following results:
a)I changed your link ‘Clients’ from https://www.media-accountants.com/#clients
to #clients
and page scrolling worked as expected.
b)I created a test link within the content (not in the navigation menu) with href https://www.media-accountants.com/#clients
and it worked as expected (no jump to top).
From the above results, it seems that the theme (or some other plugin) handles the menu links that have full/absolute URL (e.g. https://www.media-accountants.com/#clients
or /#clients
).
You should check if there’s a setting in your theme to disable this functionality (or maybe contact its developer) and let ‘Page scroll to id’ do its thing or disable other menu-related plugins (if any).
