I have tried to solve this error by below Query, but not successed.

========================================================================

SELECT * FROM cmsContentVersion

WHERE

cmsContentVersion.VersionId NOT IN (SELECT VersionId FROM cmsDocument)

=========================================================================

delete from cmsPreviewXml where nodeId in (select id from umbracoNode where trashed=1)

delete from cmsContentVersion where contentId in (select id from umbracoNode where trashed=1)

delete  from cmsDocument where nodeId in (select id from umbracoNode where trashed=1)

delete  from cmsContentXML where nodeId in (select id from umbracoNode where trashed=1)

delete  from cmsContent where nodeId in (select id from umbracoNode where trashed=1)

delete  from cmsPropertyData where contentNodeId in (select id from umbracoNode where trashed=1)

delete  from umbracoUser2NodePermission where nodeId in (select id from umbracoNode where trashed=1)

delete  from umbracoNode where trashed=1;

After doing all the above, Issue persist.

I've just recycled ApplicationPool and Restarted Application and Its work.

but unfortunately, after 2 days, same issue faced again for same site.

How can i fix this permanent?

I'm using umbraco version 4.11.10
