Error in Confluence logs: "The supplied editor content could not be converted to storage format"


A user filed a ticket as he can't publish a page. Pretty normal page upon checking, with text and images snipped to the page.

You can't previous and update the page though. Clicking update will tell you there is an error so I dived in the logs and saw that message.

Any help would be greatly appreciated.


Kind regards,

Hi Francis,

By any chance, was the content copy and pasted from anywhere else in order to create the page? 

If you were to make a copy of the page, are you able to preview and save that?

Please also confirm your Confluence version with me.

Thank you!



Hi Shannon,

Thanks for getting back to me. I know this isn't the official support channel but glad to know the Atlassian team is here as well.

Current confluence version is 6.2.3. Its a bit off from the latest and we've been holding back upgrades due to issues with our DB (not supported anymore), but we are fixing that soon.

The user hasn't gotten back to me, and I assume he must have resolved the issue. I pointed him to a community post that outlined what others did to resolve the issue (new page and upload the content again) and hasn't come back to me again (might have worked and didn't bother anymore to reply to IT support queries).

An interesting suggestion though on copying the page. The thing is the page wasn't being published yet so we couldn't do it. We couldn't even view source of the page.

Let me know if you need more information.


Kind regards,


Had a look, issue has been resolved as the user just created a new page and deleted the old one. :)




Great to hear! The reason I asked about copy/paste is when you get content from another location it sometimes copies things besides the text you can see, and it could cause errors like that. So it's probably the reason a new page worked fine.

Take care, and have a pleasant weekend.



Noted, Shannon, thanks. 

The user was an experienced Confluence user and just clips images from another site and pasted it on the page (which I normally do in most cases). It was just weird that it wasn't working this time, though we're glad creating a new page and doing it again worked.


Kind regards,
