Visit ‘Settings’ and then navigate to ‘Legal’.
Click on ‘Online store’ and then ‘Pages’.
Create a new page by clicking ‘Add page’.
Click on ‘Save’.
Step 2: replace your navigation menu button
Then, make the button link to the right page by selecting the new page you’ve just created in the ‘Link’ box.
Click ‘Add’ to finish.
Make sure to delete your previous menu button, so visitors can’t access the other page (with the display error).
