• Hello

    I am using the plugin Query Monitor and it shows me an error – please take a look.

    Cannot modify header information – headers already sent by (output started at //public_html/wp-includes/functions.php:5275)
    units 14

    wp-content/plugins/cloudflare/src/WordPress/HTTP2ServerPush.php:79
    header()
    wp-content/plugins/cloudflare/src/WordPress/HTTP2ServerPush.php:79
    CF\WordPress\HTTP2ServerPush::http2LinkPreloadHeader()
    Unknown location
    apply_filters('script_loader_src')
    wp-content/plugins/query-monitor/collectors/assets.php:285
    do_action('shutdown')
    wp-includes/load.php:1102
    shutdown_action_hook()
    Unknown location

    What should I do? What did I do wrong?
    Thanks
