Localization issues 2.8.5.2 and buddypress

Localization issues happened to 2.8.5.2 and buddypress .
I installed WPML and buddypress multilingual packages to test, but it does not work. prompts a issue that is server internal error 500.
Maybe that is compatilbe issue with buddypress 1.2, because of release note said " looking forward to adapt it to buddypress 1.1", but i can not make sure, please give me more suggestions , thanks.
