PHP error : NavigationContext::fetchSectionNodes

[khunbkk]

Hi,

In my admin panel, the left frame (left.php3) is blank. This applies also to the main frame if I click on the /admin/report link. Everything else is OK.

- Parallels Plesk Panel 10.1.1 CentOS 5 1010110120.18

- in /usr/local/psa/admin/logs/httpsd_access_log:

"GET /plesk/admin/report HTTP/1.1" 500
"GET /left.php3 HTTP/1.1" 500

- in /var/log/sw-cp-server/error_log log I can find:

PHP Fatal error: Call to undefined method NavigationContext::fetchSectionNodes() in /usr/local/psa/admin/plib/NavigationContext.php on line 69


I cannot find any reference to that PHP fatal error
Does anyone know what it is and how to solve it ?

Thanks.
