Forbidden (403) Encountered a 403 - Forbidden error while loading this page.
The JIRA instance is sitting behind a proxy and using basic authentication.
Add the line, RequestHeader unset Authorization, to the apache proxy configuration block to remove the authorization header.
<Location /jira> RequestHeader unset Authorization ProxyPreserveHost On ProxyPass /jira http://otherhost/jira ProxyPassReverse /jira http://otherhost/jira </Location>
Don't forget to add the mod_headers module, otherwise the authorisation header may not work properly.
