WordPress MU

Hello,

i transferred a WPMU setup from my local Computer to a real Server. Everything works fine except the permalinks of the PAGES on the mainblog won't work. I always get redirected to the index.

for instance: http://www.myblog.com/subblog/page1 would work.
but http://www.myblog.com/page1 doesn't. It works perfectly on my localhost with mamp. However it won't work on the real server.

If i enter myblog.com/page1 (i have %/postname/ as permalink structure) i get alwayss redirected to myblog.com.

Any ideas?
