You will have to remove the following block from the Xml file if you donÃ¢â¬â¢t want to show language selector at a particular page. For that you find the Ã¢â¬ËPage.XmlÃ¢â¬â¢ available at the following location.
In this file, you will find
<block type="page/html_header" name="header" as="header">
In which you find another block like this
<block type="page/switch" name="store_language" as="store_language" template="page/switch/languages.phtml"/>
Put comment line for this block if you donÃ¢â¬â¢t want language selector on any page.
I Hope this will help you.
