In some instances, when changes are made in Site Editor, the changes are not visible in the 2.x Open Data site. The updates can be saved, but when the View Site option is clicked, the changes are not visible. Clearing the browser cache or viewing the updates in a different web browser does not resolve the issue.
This issue occurs when a legacy site has the same subdomain as the 2.x Open Data site. This typically occurs after upgrading a legacy site with a custom domain and attempting to make changes to the 2.x Open Data site. Since the legacy site is the public site that allows users to design the 2.x Open Data site before making the site live, the site URL on the legacy site and the 2.x Open Data site appear to be the same.
