I have an issue with a Gliffy diagram not showing in Confluence. In edit mode it's visible but when pressing "save" and going back to Confluence it takes 2 seconds and it's gone on the page. When moving the mouse over the image area an image icon can be seen but the diagram is not visible. Other diagrams on the same page are visible.
Selecting "Full mode" in confluence will display the diagram.
I've looked on some older cases where the same issue has been discussed and where the fix has been to move the diagram to the upper left corner but it does not fix my issue.
