Hello,
Starting from BuddyPress 3.0 we have removed support for the deprecated and unsupported bbPress 1.x that was bundled with BuddyPress.
As written in our release post:
Most notably, the Legacy Forums component has been removed after 9 years of service. If your site was using Legacy Forums, you need to migrate to the bbPress plugin.
And here is our general bbPress 2.x forum installation guide:
Installing Group and Sitewide Forums
So, @m1000, please follow the migration guide and move everything forum-related to bbPress 2.x, which is faster and overall works better.
But I have bbpress 2.5.14 on the website, tested it under default WP themes.
Looks like there was removed groups forum activation from create.php
<?php if ( bp_is_active( 'forums' ) ) : ?>
<h4><?php _e( 'Group Forums', 'buddypress' ); ?></h4>
<?php if ( bp_forums_is_installed_correctly() ) : ?>
<p><?php _e( 'Should this group have a forum?', 'buddypress' ); ?></p>
<div class="checkbox">
<label for="group-show-forum"><input type="checkbox" name="group-show-forum" id="group-show-forum" value="1"<?php checked( bp_get_new_group_enable_forum(), true, true ); ?> /> <?php _e( 'Enable discussion forum', 'buddypress' ); ?></label>
</div>
<?php elseif ( is_super_admin() ) : ?>
<p><?php printf( __( '<strong>Attention Site Admin:</strong> Group forums require the <a href="%s">correct setup and configuration</a> of a bbPress installation.', 'buddypress' ), bp_core_do_network_admin() ? network_admin_url( 'settings.php?page=bb-forums-setup' ) : admin_url( 'admin.php?page=bb-forums-setup' ) ); ?></p>
<?php endif; ?>
<?php endif; ?>
That code controls a setting. It has nothing to do with the actual navigation bar. I am confused as to what exactly you are reporting is wrong.
Yes, I know. I have enabled buddypress legacy and when I go to group manage -> forum and I try to enable forum it stays inactive – https://imgur.com/Bc5DTL4 I also selected child forum for the group.
I have enabled group forums – https://imgur.com/jakMcKg
We don’t have enough information to figure out what the cause might be yet, I think we will need to try to reproduce the problem, but it doesn’t seem to be unique to your site, so I’ve created a bug report at https://buddypress.trac.wordpress.org/ticket/7844 — please keep an eye on that for updates.
