Solving indexing issues for password-protected sites

To bypass PHP timeout issues, FacetWP’s indexer makes a series of HTTP requests to itself. If your site uses HTTP Basic Authentication (.htpasswd), you’ll need to tell FacetWP how to log in.

NOTE: Use the HTTP Basic Authentication login, NOT a WordPress login

Add the following into functions.php or into the Custom Hooks plugin:

add_filter( 'http_request_args', function( $args, $url ) {
    if ( 0 === strpos( $url, get_site_url() ) ) {
        $args['headers'] = array(
            'Authorization' => 'Basic ' . base64_encode( 'YOUR_USERNAME:YOUR_PASSWORD' )
    return $args;
}, 10, 2 );
