We have a problem viewing and editing gliffy diagrams.
The gilffy diagram does not show on the page.
In Edit mode I can see the macro holder and I can click "edit" I get to the "Gliffy diagram properties" dialogue. If I click the "Edit diagram" button I get a blank page. After clicking the "Update" button in the same dialogue I was able to edit the diagram and save. Then when the page was saved, the Gliffy was visible.
What is going on?
