i have set up a redirect to my test server for now. i saw that my template pages with 2.0.1 were simply overwritten without applying the defaults. this merged the menu bar at the top into one. i guess you have to create a new template for each language and start everything from scratch. this is very tedious ...
why didn't you offer the possibility to run 1.1.4 parallel to 2.0.1, so that people can decide to switch over little by little.now the whole website is overwritten with 2.0.1 and there is no way back. luckily i haven't updated this for my other customers yet.
