Remove ?language=en parameter from URL

[ivok]

Hi,

 

in GWT I have big number of pages with duplicate titles, for example:

 

www.mysite.com/abc.html

 

and

 

www.mysite.com/abc.html?lanugage=en

 

 

How can I remove the language parameter or redirect it to the same page without the language=en?

 

Add ons installed - SEO URL 5 and Modular Header Tags

 

Version of OSC 2.3.3

 

Thanks

 

P.S. The shop is one language only - EN
