Hello,
I couldn’t add a comment section at the bottom of Page before. The comment only can works on Post.
I’ve turned on any setup about comment in the Settings, but it still not work.
To solve this problem, I downloaded the comment plugin – wpDiscuz. But the issue still not be solved.
Finally, I added a comment block at the bottom of the Page through the Gutenberg editor, and it actually showed up on the page.
But now we have a new problem. The comment widget cannot apply plugin styles. It is also can’t to modify the content. How can i change the content and style of the comment section on the Page?
