CodePudding user response：

Before accessing an index, try checking that the $screens is indeed an array using the is_array() function.

if ( is_array( $screens ) && is_array(  $screens['kc-css'] )

CodePudding user response：

You get errors when you don't have values in the array. So when you use array try to check it first.

if (!empty($screens['kc-css']))
