Hi Sandra,
to remove the “comments are closed” strings, you can do one of the following:
1). Go to “Localization” menu, enter the phrase exactly as it appears on the website into the “Old” box, and leave the “New” box blank. Then save your changes.
2). Go to “Appearance -> Editor” and add the following line of code to style.css:
#nocomments { display: none !important; }
Sincerely,
Andrew | Satori
