The comments in the posts are dark in color and do not appear. I didn't find where to change the color of the comments font. Can you help?

Hello @Fernando D'Amico,

There's no way how to change the color of Comments font separately. I'm adding your request to our wish list.

Comments font colour changes accordingly with the post text colour. You can change it in your Post page Design settings. I advise you to change 'Text style and colour'. But it's interesting because in your case post text shouldn't be visible as well.

Can you give me your website address? It would help me to address the issue better.
