Hello,

1-You can change the “Read more” directly in theme files. Find this folder inside your theme folder: specular\includes\view\blog\
The string is present in all files inside it. Find the one that you are using. Save changes and refresh the page.
Or you can use the pot file. Read this article for more: https://support.ellethemes.com/?ht_kb=translate-site-using-po-mo-files

2-Please add this code into your Custom Css box:

.single .blog-article #comments {  
    display: none;
}

Let me know.

Best regards!
