How to remove comments on attachments

Hi,

This is not related to the theme, but to how WordPress works. You can find the answer to your question in this post https://www.wpbeginner.com/wp-tutorials/how-to-disable-comments-on-wordpress-media-attachments/

Hope it helps.

That’s very helpful. Thank you Dragan. I’ve now disabled all comments. Do you know if there’s a quick way to delete all the ones that have already been left?

No problem. As for batch deleting the comments, I don’t know of a way.
