Error message:“The content on this page has either been modified by another user, or you have already submitted modifications using this form. As a result, your changes cannot be saved.”
What does the error mean?Note: Firstly, it’s important to note that this error message doesn’t denote a problem with your website, but more with the way the website is being accessed or used. The error is slightly misleading and prone to causing confusion (and is subject to review by Drupal maintainers) in that it displays in two possible scenarios, outlined below:
- A user edits a content page, saves the changes and then uses the back button to navigate back to the editor page, makes additional changes, and saves.
- Two different users attempt to edit the same content page at the same time. The second user to click the save button will receive this error.
