There are times when the system will advise you that the page you are working on is no longer linked or associated with the correct version of the translated page. When this happens, you must update the link manually and review the content of both pages to ensure they are properly synchronized in terms of their content.
With the page open in the Page Editor, go to the Translation tab.
In the This page is a translation of another page section, click on the link beside the Change Page field.
From the Choose Page dialog, select the page to re-associate the current page with.
Click OK.
Click Save.
Be sure to review both the primary and secondary language pages to ensure the content is current and correct on both sites.
