After upgrade Plesk 11.5.30 to 12.0.18 I first got error 500 message, which where fixed by running:
/usr/local/psa/admin/bin/nginxmng --enable
Then I could login into Plesk, but I keep getting the following message:

I tried a reinstall of plesk-lmlib with:
# yum reinstall ./plesk-lmlib-0.0.4-591.14052818.x86_64.rpm
which installed fine, but didn't help.
The folder does exists and contains the following files and folders (which wheren't there before the install):
# authorizer.lock container.lock root root.lock sleep_storage.lock
What to do now?
