Meta Keywords Not found

Hello @ach1992

Thank you for contacting the support.

Google does not honor that tag anymore and dropped that long back. You can read the post here:

With that said, if you still want to show the tag, you can add the following filter to your theme’s functions.php file:

Hope that helps.
