Why can't I comment on what I said in my QQ space, saying it's permission setting?

In this case, I suggest refreshing the webpage so that I can definitely give my comments. Set the space to talk about comments as follows:

1, log in to your qq, and click the space icon as shown in the figure;

2. After entering the space, click the permission settings under the settings icon;

3. Click the comment message on the left to prevent harassment, and then click the option on the right as needed;

4. After modification, you will be prompted to save the settings successfully.
