Hello, after installing the plugin Yoast SEO [wordpress-seo] there are some errors inside admin area (plugins.php page):

And after activating the plugin this is displayed as text inside both administration&frontend area (it's before declaration in source html code):

 */
if ( ! function_exists( 'add_filter' ) ) {
    header( 'Status: 403 Forbidden' );
    header( 'HTTP/1.1 403 Forbidden' );
    exit();
}

if ( ! defined( 'WPSEO_FILE' ) ) {
    define( 'WPSEO_FILE', __FILE__ );
}

// Load the Yoast SEO plugin.
require_once dirname( WPSEO_FILE ) . '/wp-seo-main.php';

• Compilation issues are related with this issue Update guzzlehttp library Yoast/wordpress-seo#17497. It can be avoided with the manual building of plugin and adjusting \each calls to each in lines mentioned in the log.
• There is a next problem due to this issue empty() isset() malfunction peachpiecompiler/peachpie#979.
• And the last problem is solved by Fix dictionary path separators #118
