When I try to google search my web address, the follow comes up as the meta description

"A description for this result is not available because of this site's robots.txt – learn more."

The website I have tried to edit the robots.txt (downloaded the WP Robot plugin) and although I have changed it to

User-agent: *
Disallow: /wp-admin/
Disallow: /wp-includes/

The robots.txt still appears as

User-agent: *
Disallow: /

I have Yoast SEO, WP Robots, and Salient's Theme Nectar. If anyone might be able to provide me with a solution that would update the robots (or where to go from here) that would be incredibly helpful!
