Hi Debora,

I don't understand your probelm completely but I don't think anything is
in danger.

What happens if you call your normal url and add


to the end of it (or in case there are already params add


). Then hit enter. Does it stay there in the address bar? If yes, check
relative links to other pages of your website in your website menu. Is
the string ?ref=friendly_test appended to the links?

Check Google for links to your website

But what strikes me, is that the most affected language is Chinese(Simpl.) and just one or two URL's in Spanish/English... It seems to be a PHP problem, but I really don't now IF it's TYPO3 or PHP or both...
