Problems opening system / configuration

[dgruhn]

As soon as I open system / configuration the error appears:

Fatal error: Uncaught Error: Class 'Magestore_Magenotification_Helper_Data' not found in /var/www/vhosts//httpdocs3/app/Mage.php:593 Stack trace: #0 /var/www/vhosts//httpdocs3/app/code/core/Mage/Adminhtml/Block/System/Config/Tabs.php(117): Mage::helper('magenotificatio...') #1 /var/www/vhosts//httpdocs3/app/code/core/Mage/Adminhtml/controllers/System/ConfigController.php(104): Mage_Adminhtml_Block_System_Config_Tabs->initTabs() #2 /var/www/vhosts//httpdocs3/app/code/core/Mage/Core/Controller/Varien/Action.php(437): Mage_Adminhtml_System_ConfigController->editAction() #3 /var/www/vhosts//httpdocs3/app/code/core/Mage/Core/Controller/Varien/Router/Standard.php(262): Mage_Core_Controller_Varien_Action->dispatch('edit') #4 /var/www/vhosts//httpdocs3/app/code/core/Mage/Core/Controller/Varien/Front.php(192): Mage_Core_Controller_Varien_Router_Standard->match(Object(Mage in /var/www/vhosts/***/httpdocs3/app/Mage.php on line 593

Magento Version 1.9.3.1 to OpenMage LTS 19.4.7

This probably related to corrupted Magestore_Magenotification extension and not related to openmage. Try to put this file in app/code/local/Magestore/Magenotification/Helper/Data.php.
