Hi,
did you really meant to post in this group? This is Liferay Polish user group forum where we mostly discuss in Polish language. While most of us do speak English there is rather small subset of Liferay's community hanging around here. You will significantly increase you chances to get an answer by posting in Liferay's English forums: https://www.liferay.com/community/forums/-/message_boards/category/239390!
best,
Milen
