It seems like after update, Defender is IP blocking our users

Hi there,

We have had users getting IP blocked today after the defender update and now I can’t get into the site to turn defender off (and I’m being blocked too). Just alerting you to the fact there might be a bug with the defender update you issued today!

    Hi Brandon,

    Apologies for this, do you have a mobile phone you could perhaps use to login with?

    Admin IP’s are usually whitelisted, but if your IP changed, then it will not be in the whitelist.

    Using a mobile should hopefully allow you back in, then you could remove the IP’s

    Failing that, Can you send your details using the following contact form:

    https://premium.wpmudev.org/contact/#i-have-a-different-question

    Alternatively you can email direct to contact@wpmudev.org

    Mark for attn: Vaughan

    Include a ref URL to this thread.

    Please include the following details;

    – Site login details (super-admin if on multisite)

    – Your current IP address, you can get the IP by visiting http://whatsmyip.org

    Thanks

    Hi Ian,

    The white screen sounds unrelated to the issue in this thread, could you please open a new thread for your particular issue.

    To get back into your site, you can use FTP or your CPanel filemanager.

    Navigate to /wp-content/plugins

    Now delete the Hummingbird folder.

    You should now be able to get into your site.

    Hope this helps

    Hi Brandon,

    You can also try adding the following to a mu-plugin.

    This should then prevent Admin users at least from being locked out.

    Create a file called defender_disable_admin_lockout.php

    Add the following code:

    <?php
    add_filter( 'ip_lockout_default_whitelist_ip', function ( $ips ) {
    if ( current_user_can( 'manage_options' ) ) {
    $ips[] = WD_Utils::get_user_ip();
    }

    return $ips;
    } );

    Now upload this file to;

    /wp-content/mu-plugins/

    If mu-plugins folder doesn’t exist, create it first.

    Hope this helps
