How to remove index meta tag <meta name="robots" content="index, follow">

Question

I need to remove this line <meta name="robots" content="index, follow"> on my site for the accessibility mode.

I successfully added the <meta name="robots" content="noindex, follow"> by calling add_action( 'wp_head', 'wp_no_robots', 1); but it shows both metatags

 <meta name="robots" content="noindex,follow"> <meta name="robots" content="index, follow">  

I didn't find the way to remove the index metatag line.

Answer 1

Rather than using the

add_action( 'wp_head', 'wp_no_robots', 1 );

Try using

add_filter( 'wp_robots', 'wp_robots_no_robots' );

In your code you are actually trying to add one more function call to pre called function rather than just changing its value to noindex. Use add_filter instead. :)
