Hi BNB ,
Thanks for reaching out to us!
It looks like the Chatra team already gave a pretty detailed instruction on how to do this but here are the steps with videos:
Then make sure that you have Chatra installed on your site.
You can follow their steps here:
Get started with Chatra
Then go to WordPress' Additional CSS then paste the custom CSS onto your site:
visibility: hidden !important;
opacity: 0 !important;
And that should be it! 😄
Let me know if it worked.
