If you encounter an issue where the old URL is being redirected after changing the page URL in Wix, try the following steps:
Clear your browser cache: It’s possible that the browser has cached the previous URL. Clear the cache and reload the page to fetch the latest version.
Check redirect settings in Wix: Go to Dashboard > SEO > Redirect Manager(Alternatively, you can type “Redirect” into the search box at the top of the dashboard to find the settings).
