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'
