症状

In Jira Service Management, when a new user logs in for the first time, he/she is presented with an empty welcome page:

診断

1. This only happens when visiting Jira's Base URL and trying to log in there e.g. http://localhost:8712/jira
2. This doesn't happen when trying to log in from Jira Service Management Help Center e.g. http://localhost:8712/jira/servicedesk/customer/portals
3. uBlock Origin is integrated in the browser and enabled

原因

uBlock Origin is somehow blocking the page content from being displayed properly.

ソリューション

Disable uBlock Origin for the page OR Use a browser which doesn't have this add-on.
