XF 1.5 Problem after server update

[hollosch]

Hi, i got following error after updating my server and xenforo to 1.5.22:

An exception occurred: Class 'SV_ElasticEss_XenForo_ControllerPublic_Thread' not found in /data/vhosts/example.com/httpdocs/library/XenForo/FrontController.php on line 481

1. XenForo_FrontController->_getValidatedController() in XenForo/FrontController.php at line 361
2. XenForo_FrontController->dispatch() in XenForo/FrontController.php at line 152
3. XenForo_FrontController->run() in /data/vhosts/regio-portal.wiki/httpdocs/index.php at line 13

What can be the problem ?

Class 'SV_ElasticEss_XenForo_ControllerPublic_Thread' not found

This is the problem.
