Problem

Saving or deleting image files fails and results in the following exception in the log:

com.atlassian.confluence.pages.exceptions.ExternalChangesException: Unable to save changes to unreconciled page null
at com.atlassian.confluence.internal.content.collab.DefaultContentReconciliationManager.reconcileIfNeeded(DefaultContentReconciliationManager.java:149)

This affects operations with image files within the apps:

In particular, the following functions in these apps are affected:

Linchpin User Profiles

  • Profile picture and profile background cannot be saved or deleted.

  • LDAP Sync:

    • Profile picture cannot be saved.

    • Old profile picture cannot be deleted. Exception leads to abort and rollback of the complete LDAP sync, therefore the LDAP sync generally does not work anymore and no profile data is updated.

Linchpin Events

  • Background image cannot be saved or deleted.

Linchpin Theme

  • Background image and logo cannot be saved or deleted.
