Squid logformat problem

Opensuse 11.0 / Squid 3.0 Stable5

I want to change the logformat in the /var/log/squid/access.log. Any changes to the logformat line in squid.conf takes no effect in the access.log. The access file definition is “/var/log/squid/access.log squid”. The logformat definition line is “logformat squid %{%d.%m.%Y}tl %{%H:%M:%S}tl %ts.%03tu %6tr %>a %Ss/%03Hs %<st %rm %ru %un %Sh/%<A %mt”. With Opensuse 10.3 and Squid 2.7 or so it runs perfect. I have Opensuse 11.0 new installed.
Any tipps and ideas?

Sorry for my bad english.

11.0 uses squid 3.0. You might want to check the squid documentation to see if the directives changed between the versions.
