Dear all, I've correctly installed the last version of MediaWiki on the server with Ubuntu 7.04. I've setup also the favicon entry in the LocalSettings.php. When I start the wiki with Firefox (with Firebug enabled) I receive the following error message: syntax error http://xxxxx/wiki/index.php?title=-&action=raw&gen=js&useskin=mo... index.php (Line 3) The "Error" message is shown also in the TAB close to the favicon.

This url corresponds with custom wiki javascript (ie. Mediawiki:Common.js, Mediawiki:Monobook.js...). Check that url and verify that it's in fact javascript. If your wiki is private, you may need to add an entry for it on the whitelist.
