    How about this according to Query Monitor:
    Use of undefined constant ‘init’ – assumed ‘‘init’’ (this will throw an Error in a future version of PHP)

    Hi Have the same problem and tried this code but still not much change. In fact now dashboard and few other pages like Menu are loading slowly..

  5. I have the same issue. Plugins Admin Page loading slow or returning error.

    The above code had no impact.

    define( ‘WP_HTTP_BLOCK_EXTERNAL’, true );
    define( ‘AUTOMATIC_UPDATER_DISABLED’, true );
    define( ‘WP_AUTO_UPDATE_CORE’, false );

    This works but blocking external is not a viable option if you have outgoing request aside from updates.


  6. Some issue with cloudflare DNS , it is blocking the hits thinking it is an attack on our server. The issue only arises when there are a huge number of hits within short span of time.
