The SVN version might have broken your setup now, please do not use svn versions on production systems.
First delete all websites that you created in ispconfig and wait afew minutes so that the sites and users get deleted from your system.
Then uninstall ispconfig by downloading the ispconfig 126.96.36.199 tar.gz and executing the uninstall.php script. Then reinstall ispconfig 188.8.131.52 from tar.gz.
Install only the jailkit version mentioned in the perfect setup guide as this is the one that is tested and known to work in that configuration.
