+    Your changes have been rejected because you exceeded the time limit
+    of [% constants.MAX_TOKEN_AGE FILTER html %] days before submitting your
+    changes to [% script_name FILTER html %]. Your page may have been displayed
+    for too long, or old changes have been resubmitted by accident.

+  [% ELSIF reason == "missing_token" %]
+    It looks like you didn't come from the right page.
+    One reason could be that you entered the URL in the address bar of your
+    web browser directly, which should be safe. Another reason could be that
+    you clicked on a URL which redirected you here <b>without your consent</b>.
+
+  [% ELSIF reason == "invalid_token" %]
+    You submitted changes to [% script_name FILTER html %] with an invalid
+    token, which may indicate that someone tried to abuse you, for instance
+    by making you click on a URL which redirected you here <b>without your
+    consent</b>.
