Check the extension for trailing whitespace at the end of the file (after the ?>) or just remove the ?> entirely and see if that fixes it.

I was wondering since a few days why I have not received any new information about the mods made on my wiki. Clicking on the RSS button, I get the following message :

Erreur d'analyse XML : instruction de traitement XML ou texte pas au début d'une entité externe Emplacement : http://www.arvernes.com/wiki/index.php? title=Special:Recentchanges&feed=rss Numéro de ligne 2, Colonne 1 :<?xml version="1.0" encoding="utf-8"?> ^

Here : http://www.arvernes.com/wiki/index.php? title=Special:Recentchanges&feed=rss

I do not know where to look at to solve that. Thank you. Francois

Finally I found the culprit; the extension : SpecialLastUserLogin2.php. I got to deactivate it, to get the rss feed of my wiki back to normal as I do not know how to fix it. I do not if someone else got this problem though. Francois
