Thread:Project:Support desk/No Messages of my extension in Special:Allmessages

Hello. So far, on my extension FrequentPatternTagCloud (http://www.mediawiki.org/wiki/Extension:FrequentPatternTagCloud) the i18n-messages are displayed and translated. Now I've tested the extension on an Ubuntu server. I think the messages are not registered, because the specialpage Special:Allmessages don't show the defined messages of my extension. But I normally register the i18n file via $wgExtensionMessagesFiles.

The following versions are used: MediaWiki 1.16.4 PHP       5.3.2-1ubuntu4.10 (apache2handler) MySQL     5.1.41-3ubuntu12.10

Can anyone help?
