Changing language leads to redirect loop

Hello,

my shop language is at the moment English. But I want to change it to Thai. When I do so, the homepage looks good, but I can’t access the products and longer. The websites loads and loads and nothing happens.

Does it have to do with the links? Usually the links are:
/product/something

but in Thai it changes to Thai letters. The browser displays the letters correctly, but internally it’s a long long URL, for example:
รีวิว AuraMilk สินค้าขายดี ผิวขาวใสทันทีหลังใช้ becomes:
http://glamorwithareeya.com/%e0%b8%a3%e0%b8%b5%e0%b8%a7%e0%b8%b4%e0%b8%a7-auramilk/

I don’t know if it has to do with the redirect loop, but I couldn’t find any information online about the issue. And I really want to change the language, because I’m targeting Thai customers, thus an English shop would be not optimal.

I’d be glad about any kind of help!
