    Have you had any reports of a fatal error on update to v.4.6? The update has failed on one site with the following error logged:

    [12-Aug-2024 07:24:51 UTC]     The update for 'ninjafirewall' contained a fatal error. The previously installed version has been restored.
    [12-Aug-2024 07:24:51 UTC]   Automatic plugin updates complete.
    [12-Aug-2024 07:24:51 UTC] Automatic updates complete.

    I have tried disabling all other plugins and enabling a Twenty^ theme, but the update still fails with the same error. Another site on the same server has updated to v.4.6 without any issues. There are three issues in Site Health:

    An active PHP session was detected
    The REST API encountered an error
    Your site could not complete a loopback request

    But these appear to be browser-cache related, as when I open the back-end in a private browser window, they do not appear in Site Health. If I try to update NinjaFirewall in that same private browser session with no Site Health issues, I again get: “Plugin could not be activated because it triggered a fatal error“.

    Another person had the same issue: https://www.ads-software.com/support/topic/update-to-4-6-generates-a-fatal-error/
    But I can’t reproduce it yet.

    Do you have another website in a parent folder with NinjaFirewall installed ?

    Do you have another website in a parent folder with NinjaFirewall installed ?

    Yes! The website in the parent folder has NinjaFirewall installed and updated to 4.6 without any problems. There are two sites in child folders with NinjaFirewall installed. Site A updated to 4.6, but Site B has the problem described above.

    Can you run this code on site B ? Create a script named ‘test.php’, and add this code:

    <?php
    header('Content-type: text/plain');
    require 'wp-config.php';
    $res =  get_declared_classes();
    foreach( $res as $class ) {
       if ( $class == 'NinjaFirewall_helpers') {
          echo "NinjaFirewall_helpers is declared\n";
       }
    }

    Go to https://site B/test.php. Does it display the “NinjaFirewall_helpers is declared” message?

    Yes, the “NinjaFirewall_helpers is declared” message is returned.

    The child site inherits the parent site’s classes declaration. That’s very annoying.
    Can you try that new version: https://nintechnet.com/ninjafirewall.4.6.zip

    Perfect. The new version activates on the child site without any problems at all. Thanks!
