[Typo3] Strange behaviour after upgrade to last version

I think example_languageMenu.php was used for the old language selection
system. I am using now the extension "Language Selection" 
(sr_language_menu) and I don't find where (in wich file) to put this 
"_top" string. Or is it in the Setup or constant area of the template in 
the BE of Typo3 ?
