Import Bookmaklet

When I try to use “Import Bookmaklet” using Chrome I get the message “Language eu is not supported by LingQ"
What does it mean? Does it depend on source side?

“eu” is the ISO language code for Basque. The Import Bookmarklet is reliant upon Google’s language detection software, so it means that Google thinks the text is in Basque.

What text are you trying to import?
