Hi Tosin.
Please use the following code for diabling buttons:-

// Disable activity comment.
add_filter( 'bp_activity_can_comment', '__return_false' );
// Disable activity favourite.
add_filter( 'bp_activity_can_favorite', '__return_false' );
// Disable activity deletion.
add_filter( 'bp_activity_user_can_delete', '__return_false' );

and you can use the following for blog post comment recording

// Disable blog comment recording.
add_filter( "bp_activity_post_pre_comment", '__return_false' );
add_filter( "bp_activity_pre_transition_post_type_comment_status", '__return_true' );

You should also disable the Blog/Forum post commenting in the Dashboard->Settings->BuddyPress->Options tab.

Hi Tosin,
My suggestion would be override the buddypress/activity/entry.php and remove the code.

There are filters to disable the buttons but they will affect all other locations for these buttons.

If that is fine, we can use use the filters instead.

Hi Tosin,
Thank you for the question.

There are always the way to disable it. The solution is good or not will depend on theme/template pack being used.

Which theme and template pack are you using? If you are using a custom theme, the theme developer is the best person to approach.
