In the previous version of qTranslate I couldn't add the site's main title and description in more than one language.
There was seem to be a hack to it and add somthing like
<---:en:---here in english ---:en: --->
etc. for other languages, (don't sure it's the correct syntax , but something like that I copied from the qTranslate official forums.
It didn't work and I had to statically insert it in the template , conditioning the language that is being vieed.
Have this issue have been solved in the new version of qTranslate?
I must say that between all the different plugins the exist for multi language in WordPress, qTranslate is one of the best that exist.
