BuddyPress.org

After finally being able to use Buddypress on my website I’m suffering of the problem, that the template doesn’t fit with my template. I used this tutorial to adjust my template, but it won’t work. First of all, the word “sidebar” is nowhere to be found in my HTML structure and it only has the word “contain” but not “container”.

My second problem is, that my website is german languaged. So I wondered if there is a possibility to change the systemlanguage of Buddypress to german?

Thanks in advance for helping comments!
