I have a multilingual website in three languages with more than 1000 pages that created by ZOO yootheme documentation app.

At present I have 3 links per an article for example:
.com/en/study
.com/fa/study
.com/ar/study

but the main and correct link is only en/study.

This problem is happening for all articles in all languages. It means that I have 3 time links more than real number of links and all articles are accessible from all languages.

Is there any special setting for solving this problem.

I need plugin for Easydiscuss, Where can i find it?
