We have seen this once or twice in support – there are elements in the elements table where type is set to craft\models\EntryDraft rather than craft\elements\Entry. It’s not really clear how it happens though.

You can resolve by executing the following SQL query:

UPDATE elements SET type = 'craft\elements\Entry'
WHERE type = 'craft\models\EntryDraft'

Thank you for your reply @brandonkelly, this does indeed solve the error. For others, please note you need to escape \ and the tables are usually prefixed with craft_, resulting in:

UPDATE craft_elements SET type = 'craft\\elements\\Entry' 
WHERE type = 'craft\\models\\EntryDraft'

Thanks for the solution Brandon!

Jerome is right about needing to escpape the \ characters. Although for anyone else who comes here - tables are generally only prefixed with craft_ if it used to be a Craft CMS 2 website - mine was just called elements.
