Gtranslate pro on my web site seems to work properly when opened with Internet Explorer.
Opening the same page page with Firefox works until a language page is specified.
For example, opening http://claws.eng.ua.edu/no/
will bring a Norwegian translation.
After that, going back to http://claws.eng.ua.edu
will always open pages in Norwegian and all other pages on the site as well.
Even more, English now is gone from the drop-down language menu. However, selecting a language other than English in the drop down menu will translate the page to that language.
This was tested on 3 different machines. Now I have one Firefox that is stuck in Norwegian, another in Italian and the third one in Russian. Please advise.
