Normally a diff of a rollbacked edit is shown on the rollback result page.
But on Wikimedia projects the diff is in the majority of cases not shown. Only sometimes :-/
The HTML source contains an empty table instead:
<table class='diff'> <col class='diff-marker' /> <col class='diff-content' /> <col class='diff-marker' /> <col class='diff-content' /> <tr valign='top'> <td colspan='2' class='diff-otitle'></td> <td colspan='2' class='diff-ntitle'></td> </tr> <!-- diff generator: wikidiff2 srv110 2008-09-20 22:01:18 -->
and same
<!-- diff generator: wikidiff2 srv173 2008-09-21 11:56:56 -->
A diff was shown from srv155:
<!-- diff generator: wikidiff2 srv155 2008-09-19 19:14:56 -->
<!-- diff cache key dewiki:diff:version:1.11a:oldid:48233907:newid:50914488 -->
I am unsure if it is an issue with MediaWiki code or settings of the servers.
