Wow! This is the best plugin I've used in quite a while. It works flawlessly EXCEPT for when someone actually clicks the "SAVE" button in the upper right. This always results in a "Error Saving File" message in the top center of the screen. However, the file appears to save perfectly fine, as it is there and accessible in the attached files list.
This is using JIRA 6.3.12 and the latest Draw.io from 1/2/15. Also tried with multiple browsers.
Any help? Thanks again!
