Since a few weeks (changed to new server environment) we are experiencing this issue:
Starting from a filter, ex “My Open Issues”, you get your list, clicking on an items gives you an url, ex: http://website/browse/SUP-48?filter=-1
On this page you canot edit the issue and you also can’t change the status. You get a mouse cursor that keeps turning.
When you remove the last part of the link: ?filter=-1
Then everything works fine.
The site runs behind an IIS proxy server
