Hi @Lyser,
I have checked the page and seen the problem you are referring to while clicking on the Button. But while changing the anchor directly in the Browser address bar, it worked perfectly fine. If you go through the following screenshot, you can see the Four is in the URL and it shows the Four section but the Five button is activated.
There might be something else which is the reason behind it, I would like to suggest troubleshooting the following common issue to help us to recognize the reason.
1.Theme Related Issue
2.Plugin Conflict
3.Theme Update related issue
4.Child Theme Related issue
5.CSS/JS Customization
6.Disabling Cache
7.Disabling CDN
If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
If none of the above help, please provide login credentials for your site in a secure note to examine it further, including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
