Hello,
1.6 alpha is causing major problems in the Hungarian Wikipedia. Something must have changed in the parsing of templates. We have used a "meta-template" to generate the content of Babel templates for some time; take a look at http://hu.wikipedia.org/wiki/Sablon:User_en to see what the templates look like now. (The English template should, of course, look like this: http://en.wikipedia.org/wiki/Template:User_en).
All the best, Endre/KovacsUr@huwiki
