Problem
When trying to copy an existing Confluence page, the following ERROR occurs in atlassian-confluence.log:
2015-06-05 11:21:00,803 ERROR [http-bio-8090-exec-10] [atlassian.confluence.pages.DefaultAttachmentManager] getAttachmentData Could not find data for attachment: Attachment: test.png v.1 (36971334)

Cause
The attachment has been deleted from the filesystem but the attachment is still referenced by the page the user tried to copy.
Workaround
Delete the attachment reference from the database.
This is only applicable for Confluence 5.7.x and above.
Always back up your data before performing any modifications to the database. If possible, test any alter, insert, update, or delete SQL commands on a staging server first.
Identify the ID of the attachment that needs to be deleted. From the example above, the ID would be "36971334"

delete from contentproperties where CONTENTID = 36971334; delete from content where contentid = 36971334;Restart Confluence.
