Fixed since

The problem described in this KB article is completely fixed in Parallels Plesk Panel version 10.4.x and later versions.


After upgrading Parallels Plesk Panel to version 10.0.1, the following error message is shown on the login page:

ERROR: Zend_Log_Exception
"/usr/local/psa/admin/logs/panel.log" cannot be opened with mode "a"

0: Stream.php:66
        Zend_Log_Writer_Stream->__construct(string '/usr/local/psa/admin/logs/panel.log')
1: Abstract.php:84
2: Abstract.php:31
3: Abstract.php:19
4: auth.php3:137

However, all packages and databases have been upgraded:

# rpm -q psa

# mysql -uadmin -p`cat /etc/psa/.psa.shadow` psa -e"select * from misc where param='version'"
| param   | val   |
| version | 01090 |

And the file /usr/local/psa/version is empty:
# cat /usr/local/psa/version


The post-upgrade script was not executed correctly. To fix the error, perform post-upgrade configuration repair by executing the bootstrapper script.
Bootstrapper script can be found in the directory $PRODUCT_ROOT_DIbootstrapper/.

# /usr/local/psa/bootstrapper/pp10.9.0-bootstrapper/ repair
**** Product repair completed successfully.

After repairing the configuration, you should be able to access the Control Panel.
