We have not previously had any issues with our JIRA accounts and creating issue collectors, but for one of our projects attempting to create a JIRA collector results in the embedded javascript not actually doing anything on page load.
I have put up a barebones test page up at:
http://extranet.the1stmovement.com/jira/
As you can see it's just the embedded JS copied and pasted from the JIRA control panel. I've tried even making new issue collectors in the same project, however I get the same thing. The JS is included, however, there is no issue tab visible or added to the page.
