    I updated WordPress to version 5.3 and got these warning messages on the page and everywhere else visible to everyone. Updated all plugins and still had the message, tried to backup with updraft. Also deleted the Hummingbird plugin which seems to be causing the error, but now my /wp-admin access has just completely gone, I cannot access the backend anymore. Everything it shows are the Warning-messages.

  • Hi,

    Login to your FTP using any FTP browser like Filezilla.

    and delete this file,

    /kunden/527037_72764/regiosmart_com/wp-content/advanced-cache.php

    Before deleting, you can make a copy of that file.

    Hello @shekler,

    First Disable below plugin,
    plugins/hummingbird-performance

    and wp_debug = true then change it to false. in wp_config file.

    if issue not solved then try to check whether issue form theme or plugin.

    if issue in plugin then try to check disable one by one plugin.

    I hope above suggestions helpful to you.

    Make sure you take a necessary backup before editing any files.

    Thanks & Regards.
