Hello,
I already did these steps buy without any succes.
Please see the print-screen of the activated Classic Editor Plugin that came with the theme: https://stanandrei.ro/wp-content/uploads/2020/11/ss1.png
And here I followed the steps in your screenshot but it still doesn’t work: https://stanandrei.ro/wp-content/uploads/2020/11/ss2.png
I left the two sections at the end of the page.
Thank you!
