How to remove ‘MORE FROM AUTHOR’

Hello,

I recommend you use a Single Post Template from tagDiv Cloud Library, and you can design it with tagDiv Composer.
To display the related articles or more from the author, you can use Flex Block and filter it https://www.screencast.com/t/SEmxo13Fo2X -> https://i.imgur.com/YIg3nPP.png
if you want to keep those templates the only way to remove the “more from author” tab is to use a custom CSS like this one:

.single .td-related-right{
display: none;
}

Set the code in Theme Panel ->Custom code -> Custom CSS
I hope this helps you!

Thank you!
