Hi all,
I have the same problem -- after upgrading to 2.4.0, I get this error:
[User Warning] Cookie 'bypassStaticCache' can't be set. The site started outputting was content at line 63 in /srv/web/tal-15299/beta.alt-katholisch-hannover.de/mysite/code/Page.php

The only extra module installed is the blog module; I tried removing it and running /dev/build?flush=1 again, and reinstalling the blog module, but to no avail.
Any ideas?
