    Hi, @loremipsum123.

    Glad you reached out.

    Warning messages like this display when your site has “Debug Mode” turned on. Debug mode is a method for developers to use to find issues in their code and compatibility problems with different versions of PHP (the server language WordPress uses). Debug mode is usually only used on development sites or non-live sites.

    In the meantime here’s how you can hide those warnings: in your wp-config.php file (which you can get to via SFTP or through your web host’s file manager) look for a line like this:

    define(‘WP_DEBUG’, true);

    Replace it with the following lines:

    define(‘WP_DEBUG’, true);
    define(‘WP_DEBUG_LOG’, true);
    define(‘WP_DEBUG_DISPLAY’, false);
    @ini_set(‘display_errors’, 0);

    Again, this method is normally only used for development, not on live sites.

    If you need assistance with that, your web host should be able to help. Also, there is some official documentation on that: https://codex.wordpress.org/WP_DEBUG

    Please let us know if you have further questions or need additional assistance!
