Debugging TestRail issues
When diagnosing issues with a TestRail installation or integrations with external tools, the Gurock Software support might ask you to take a look at the details of a HTTP response that is returned by TestRail. The easiest way to do is to use the Chrome web browser and its developer tools.
Simply press F12 in Chrome (Cmd + Opt + I on Mac) and a new window opens at the bottom of Chrome. Then open the Network tab, repeat the action that needs to be diagnosed, and click on the request (the entry on the left that starts with index.php?). A new area should appear on the right. Please activate the Response tab and send a screenshot of this page to the Gurock Software support:
