You should do it yourself, just get "Privatised" and "Non-Privatised" comments value and display it separately.

Can anyone help me?

I am thinking to separately display both number of "Privatised" and "Non-Privatised" comment on my blog site. 

Please help, thanks.

As I already mentioned in the above post there is a plugin conflict or conflict with the current active theme. Once you find the reason of the issue, the code provided by us will work as expected and will display the number of privatised comment.

Thanks for your information. Can you let me know how can i display the number of privatised comment?

Thanks

As I already mention the number mentioned by you does not have any relation to the wpDiscuz(the number changed before it got to wpDiscuz). Probably there is a plugin conflict or conflict with the current active theme you use. So please deactivate the plugins one by one and check after each deactivation to find the problem maker one. Also please switch some default them before checking.

Once you find the reason of the issue, the code provided by us will work as expected.

Checked and worked except the <?php comments_number

I input your code in active theme's function php, but did not work. Let me explain:

The only person who can view the privatised comment number is the comment author himself. All others can't see the privatised comment being added to <?php comments_number

Can we do it in this way, can you let me know how can i display the number of privatised comment instead?

The code did not work. <?php comments_number still shows only the visible comment.

The developers checked again and saw that the code is working as expected, could you please check it again and make sure you are adding the code in the correct way.

Any other problem is that, i can't set private/public of the comment in the wp-admin area, please see screenshot. When i click private or public, it does not have any action.

Please update the wpDiscuz Private Comments add-on to the latest version(v.7.0.3) and check again. There should not be such an issue anymore.

The code did not work. <?php comments_number still shows only the visible comment.

Please advise.
