Hey there.
I just installed jira agile 6.2.4. After configuring and answering starting steps, when I login with local pc everything is ok. But when other users login jira dashboard is empty. I googled it and found below answers but none of them solved my problem:
1. In jiraHome\tmp\websources delete all files.
2. Changed the host pc but the problem is still there.
3. Installed another version of jira(6.1) and nothing.
4. Finally by using Mozilla firebug, I found this: “Uncaught TypeError: Cannot read property '0' of undefined” which refers to this file: “com.atlassian.jira.jira-tzdetect-plugin:tzdetect-lib.js:2”
