wpml and Yet Another Related Posts Plugin (YARPP)

Yes. We actually recommend Polylang at this time. See https://polylang.wordpress.com/2013/05/03/polylang-and-yarpp/.

oh sad. i thank you for your recommendation, but well, we would not have chosen a paid plugin such a wpml if we would not have very good reasons for that. :/ i hope YARPP can be compatible soon!

I thank you for your help!
