+    Background:
+      Given I am logged in
+      And plugin is installed 'new_release'
+      And plugin is activated
+      When I go to 'wp-admin/options-general.php?page=wprocket#dashboard'

+      And activate 'wpml-multilingual-cms' plugin
+      And wpml has more than one languages
+      And wpml directory is enabled
+
+    Scenario: Open the page with directory lanaguage
+      Then no error in the console different than nowprocket page 'lazyload_css_background_images'
+      When switch to another language
+      Then I must not see any error in debug.log
+
+    Scenario: Change WPML to query string option
+      Given wpml query string is enabled
+      Then no error in the console different than nowprocket page 'lazyload_css_background_images'
