Reply To: BuddyPress Activity Page 404 Error
This sounds like it’s possibly a template issue.
To create the activity page, the activity/index.php file is called, this in turn issues the following:
<?php bp_get_template_part( 'activity/post-form' ); ?>
I’m guessing this is what’s failing, as it’s the first template file called, it calls activity/post-form.php which creates the “What’s New” input box. Is that missing from your page?
One of the issues with template files is that they can be loaded from several places depending on the configuration. But in the very least you should check you have one located in:
BP Legacy theme in use - wp-content/plugins/buddypress/bp-templates/bp-legacy/buddypress/activity/post-form.php
BP Nouveau theme in use - wp-content/plugins/buddypress/bp-templates/bp-nouveau/buddypress/activity/post-form.php
