+                GitLab QA sanity selectors validation test detected problems
+                with your merge request!
+
+                The purpose of this test is to make sure that GitLab QA tests,
+                that are entirely black-box, click-driven scenarios, do match
+                pages structure / layout in GitLab CE / EE repositories.
+
+                It looks like you have changed views / pages / selectors, and
+                these are now out of sync with what we have defined in `qa/`
+                directory.
+
+                Please update the code in `qa/` directory to make it match
+                current changes in this merge request.
+
+                For more help see documentation in `qa/page/README.md` file or
+                ask for help on #qa channel on Slack (GitLab Team only).
+
+                If you are not a Team Member, and you still need help to
+                contribute, please open an issue in GitLab QA issue tracker.
+
+                Please see errors described below.
