Yesterday I upgraded my wordpress to version 2.7.1 and quickly found out that the site layout was broken. Today I glanced over the K2 page but found no statements about this issue. But: I found a “Nightly Built” section with more up to date template versions than the officially released one. So I installed the newest Nighly from Februrary, 12th and … the issue was fixed.

You’ll find the newer templete here.
