Thread:Project:Support desk/After upgrade to 1.23.6, links displayed with corrupted text for greater than and less than brackets

Versions: MediaWiki	1.23.6 PHP	5.5.19 (cgi-fcgi) MySQL	5.1.73-log

I recently upgraded from an older version to 1.23.6. The upgrade seems to go okay, except that all the Wiki's links are displayed wrong. The actual content of the Wiki is okay, but the "build-in" links display with &amp;lt; at the beginning and &amp;gt; at the end. Looking at the source xml of one of the links, it appears as: &amp;amp;lt;searchprofile-articles&amp;amp;gt;

It appears that the intended string is getting double encoded: The less than sign is encoded to &amp;lt; and then that is re-encoded to &amp;amp;lt;

This obviously is an artifact of some part of the upgrade since it doesn't happen on a clean install. I can't find anything in the LocalSettings.php file that would explain the difference. I'm not sure where to look.
