I have installed the viadee plugin BPMN-Moderler. I try to add an existing bpmn-file to a page, but confluence prompts that either I have no rights to upload content or the file isn't a proper bpmn-file.
I have uploaded a png file before, and it worked out properly - the diagram is shown in the confluence page. But this is only a picture, I want to use the bpmn diagram.
The file I uploaded was created via camunda modeler and the bpmn syntax is correct.
How can I add the file correctly, which configuration do I need to setup in order to be able to upload bpmn files?
Thanks for help - a confluence newbie
