Auto Scroll by pressing back button

Hi there,

looks like a scripting error.
Visit the blog post, and Right Click > Inspect the page to open the browser developers tools.
Check the console tab and there you wll see several script errors. All look to be related to a CORS issue between your domain and CDN.
Check with the host/CDN provider on how to fix those issues.

Can you disable the Back to Top button option in the Customizer > Layout > Footer.

OK, next disable the GP Smooth Scroll in Appearance > GeneratePress.
Thats the only other script that would do something on a popstate event ( which is any change to the active browser history including the back button )

Let us know.

OK, thats good as it eliminates the theme scripts that do any kind of listening to popstate events ( the JS event that happens on browser active history changes such as the back button ). Which means its another script on the page.

There are 2 other scripts that are engaging on popstate events and those are in the GTM and Clarity scripts.
But before you go there, considering the scroll position shifts. Remove any other plugins that affect scrolling eg. Fixed Widgets plugin.

After that its a case of disabling other plugins and those tracking scripts to see which is the cause.

I can confirm that following a link from the cloned magento site, the Back button works correctly.
But I am not sure what you require me to do ? As the Theme has nothing to do with how those links work. And above we eliminated the only theme related scripts that could have interfered.
