Polylang

Hi guys, sorry for my bad english….i am new in wordpress…so i installed a theme which name is “onetone”, i think its responsive theme and this theme has 7 section contect so i dont have a page or article, my text, plugins and widgets are all on that theme. you can see it at “chicosantoamaro.pt” i installed a polylang plugin and create an .xml file in the /wp-content/polylang. the .xml looks like this “<wpml-config>
<admin-texts>
<key name=”onetone”>
<key name=”menu_title_0″/>
<key name=”menu_title_1″/>
<key name=”menu_title_2″/>
<key name=”menu_title_3″/>
<key name=”menu_title_4″/>
<key name=”menu_title_5″/>
<key name=”menu_title_6″/>
<key name=”section_background_0″/>
<key name=”section_background_1″/>
<key name=”section_background_2″/>
<key name=”section_background_3″/>
<key name=”section_background_4″/>
<key name=”section_background_5″/>
<key name=”section_background_6″/>
<key name=”section_background_video_0″/>
<key name=”section_background_video_1″/>
<key name=”section_background_video_2″/>
<key name=”section_background_video_3″/>
<key name=”section_background_video_4″/>
<key name=”section_background_video_5″/>
<key name=”section_background_video_6″/>
<key name=”section_css_class_0″/>
<key name=”section_css_class_1″/>
<key name=”section_css_class_2″/>
<key name=”section_css_class_3″/>
<key name=”section_css_class_4″/>
<key name=”section_css_class_5″/>
<key name=”section_css_class_6″/>
<key name=”section_content_0″/>
<key name=”section_content_1″/>
<key name=”section_content_2″/>
<key name=”section_content_3″/>
<key name=”section_content_4″/>
<key name=”section_content_5″/>
<key name=”section_content_6″/>
<key name=”menu_slug_0″/>
<key name=”menu_slug_1″/>
<key name=”menu_slug_2″/>
<key name=”menu_slug_3″/>
<key name=”menu_slug_4″/>
<key name=”menu_slug_5″/>
<key name=”menu_slug_6″/>
</key>
</admin-texts>
</wpml-config>”
in the admin area i can translate that sections but in the frontend site the language is the same, so its no change the language when for example i go to “chicosantoamaro.pt/?lang=es”
