    I am using the free version of Wordfence and I recently updated from v 7.2.4 to 7.4.2. When I tried to access the site’s WordPress dashboard after I updated Wordfence, I was unable to access the dashboard and instead received a “Fatal Error” message. An email that I received from WordPress contained the following Error Details:

    “An error of type E_ERROR was caused in line 54 of the file /var/www/wp-content/plugins/wordfence/modules/login-security/classes/controller/settings.php. Error message: Uncaught Error: Class ‘WordfenceLS\Settings\Model_DB’ not found in /var/www/wp-content/plugins/wordfence/modules/login-security/classes/controller/settings.php:54

    #6 /var/www/wp-settings.php(360): include_once(‘/var/www/wp-con

    In order to get my site back up, I restored it to a backup from a couple of days prior to when I updated Wordfence>

    Can anyone recommend a solution that will allow me to update Wordfence without the issue recurring?

  • Hey @chrishannon,

    This sounds like a WordPress plugin update that didn’t go well. Can you please try reinstalling Wordfence and let me know if it helps?

    Please let me know how it goes.

    Thanks,

    My apologies for the delay in responding, Gerroald!

    I enabled the setting to delete all data upon plugin deletion, then I deactivated and deleted Wordfence. Then, I reinstalled and activated it. Everything seems to be fine, now! Thank you for all of your help! I will start a new thread if I have any further issues.

    I have the same issue with WordPress 5.4.2 with WordPress 7.4.7.
    Plugin could not be activated because it triggered a fatal error.
    Before I deactivated this plugin, I had out of memory errors installing plugins and trying to upgrade wordpress.

    Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 67108872 bytes) in /home/<myuser>/public_html/<myusite>/wp-content/plugins/wordfence/lib/wfIssues.php on line 504
