We have several confluence pages which are blank when we try to edit them. Each of these pages have pivot table inserted in the page. All other pages are rendered properly in the editor. Catalina.out does not show any error. atlassian-confluence.log has the following error:
[confluence.impl.vcache.SynchronousExternalCache] lambda$get$11 Failed to read entry from cache 'com.atlassian.bandana.BandanaPersister': Failed due to UNCLASSIFIED_FAILURE
Confluence : v 6.6.7
Thanks,
Vaani
