Within the last few days, I applied for an Atlassian On-demand account and it was created using what I'm assuming is the latest build of JIRA,6.0-OD-07.2, (this was not an option to select in the "Versions Affected" for this issue) build 6031. As a side note, I migrated my data from 5.1.7, build 786. I no longer have the capability to search for issues using the basic search, because the pop-up to refine search criteria when clicking "Project", "Issue Type", etc, is not displayed. This does not appear to be a browser-specific issue, though I am using Google Chrome 25.0.1364.172 m. The javascript console provides the information that you can see in the attachment to this issue when any of the fields that I'm trying to refine are clicked. The advanced search criteria works as expected.
