I saw similar problems on my wiki until I rolled the parser back to the 1.11version
This could indeed be the problem - as far as I know the parser hasn't been switched to the new one on the live Wikimedia sites yet so the templates probably haven't been "translated" to work with the new preprocessor. See the base of DefaultSettings.php for the variable to alter in LocalSettings.php.
