> Discourse provides a default version for \`/robots.txt\` which can be customized by admins in \`/admin/customize/robots\`. In that page, there's a button to reset back to the default version that Discourse provides. However, there's currently a bug with the reset button where the content appears to change to some HTML document instead of the default \`robots.txt\` version when clicking the button. Refreshing the page shows the true/correct content of \`robots.txt\` which is the default version, so the reset button actually works but there's a display problem.
> 
> What causes this display problem is that we use Rails' \`render\_to\_string\` method to generate the default content for \`robots.txt\` from the template, and what we get from that method is the \`robots.txt\` content wrapped in the application layout. To fix this issue, we need to pass \`layout: false\` to the \`render\_to\_string\` method so that it renders the template without any layouts.
