Unsupported content: extension when inserting an editable draw.io diagram

[Susana Martin]

When I embed a draw.io diagram in Confluence, it only appears when the page is in edit mode. Other draw.io diagrams that don’t need to be editable display correctly without any problems. Does anyone know how to fix this?

Is this wrapped by a numbered heading macro? https://jira.atlassian.com/browse/CONFCLOUD-81707

I was having the same problem and can confirm in my case the draw.io diagram was inside a "Numbered Heading" macro template. 

The diagrams started showing up correctly as soon as I put it outside of the macro. 
I have used gliffy in the past the same way and don't remember having this issue, seem to be only for draw.io diagrams (at least in my experience).

Hi @Susana Martin

I'm sorry you're running into this issue. Could you please try clearing your browser cache and cookies (this is the most common fix)? Alternatively, try opening the page in a private/incognito window or a completely different browser if you want to instantly rule out any local caching problems. 

If you still are seeing the issue after this, let me know. But I hope this will solve the issue :) 

Best, 

MJ
