undefined method 'cms_connector_path' during browsercms 3.5.3

Hello Guys,       I tried to upgrade the browsercms project to latest version (browsercms 3.5.3). But it shows the error like undefined method 'cms_connector_path'. Any one have idea to get rid of it?

Hello Guys,       Found the solution to overcome this problem by replacing 'cms_connector_path' to 'cms.connector_path'
