Hi I updated from Plesk 10.4 to Plesk 11.0.9 (on Ubuntu 10.04) some time ago. It worked well for a few weeks but since 11. September I keep getting a "Parallels Panel key update deferral notification" every day. Now the license key is invalid. I did not change anything important in Plesk after the update to 11.0.9 (except deleting one sub-domain and adding an FTP account) The only key installed is the basic Plesk license for 10 domains. I can telnet ka.swsoft.com port 5224. The test.php from http://kb.parallels.com/en/111198 returns: Any idea whats wrong?
