Hi,

We had a page that was published. Then we edited the page and saved it as draft. The change we made was changing the template which broke the page (this is another issue, for another day) so we went to Revision History and deleted the drafts version, leaving just the published version in place.

Now we can't edit the page at all as when we try to view it we get the error message below. It's worth noting that on the page list the page still shows as "Draft (newer than published)" even though we have deleted those draft versions.

Error is:

Server Error in '/' Application.

To fix this problem just go to the draft table (sf_draft_pages) in the SQL DB, and remove all records for this specific page that contains flag  is_temp_draft = 1 .

delete from   sf_draft_pages
WHERE        (page_id = 'AB3A4477-C33E-6444-B2E5-FF0000444C51') and is_temp_draft=1

Hi,

Tarek El-Mallah approach, didnt worked for me.

On my case this happened because I changed the name of a Layout in Feather Boostrap Layout Folder. I went to backoffice(was not giving the error) associated the pages to the correct layout name, deleted the old name layout. and the error disappeared.

Best Regards,

Nelson
