BuddyBoss Platform - Posts and activities are not correctly filtered by language

Overview of the issue

If you’re using BuddyBoss Platform plugin version 2.8.80 or newer, you will encounter that posts and activities are not correctly filtered by language on feed pages.

Workaround

1. Open the file wp-content/plugins/buddyboss-platform/bp-core/compatibility/class-bb-wpml-helpers.php
2. Comment out line 83// add_filter( 'bp_init', array( $this, 'bb_prevent_translated_post_activities' ) );
3. Save the file. New posts and translations will again write activity rows for every language (existing missing entries are not retroactive).
