Language detection general
There are several ways for sites to determine the language that is displayed.
We use a standard method as recommended for websites. ie. browser cookies, operating system language
or system preference settings. If it is not able to recognize the language it will default to English.
If you have visited our test taker site before and selected one language it is saved into a cookie and remembered for your next visit.
The error you have described could indicate that the system is detecting another language than you expect.
In order to fix this error, you need to make sure that the correct languages are set on your system and that browser cookie is deleted.
