Cause
Any leftover or corrupted data in the database/index can cause this problem. When saving a page/blog, for example, if there is a broken/missing reference, Confluence can't process the request and is unable to update its content.
How to Identify the broken reference
After the request attempt is processed, the application will register its failed entry in the application logs (atlassian-confluence.log). Below is an example:

Diagnosis
For versions prior to 6.15.1, this can be caused by the following bug:
In this case, we recommend upgrading to prevent this issue from re-occurring. However, upgrading won't resolve drafts with broken references, so this can be resolved by creating a new page with the same content.
Resolution
To remove the broken reference in the drafts:
Create a new page
Copy the content from this draft to the new page
Save the new page
Remove the page with broken references
