    Hello there,

    after updating from 7.1.4 to 7.1.5 it crashes my site giving following the message:

    Fatal error: Uncaught exception ‘wfWAFStorageFileConfigException’ with message ‘Error reading Wordfence Firewall config data, configuration file could be corrupted or inaccessible.

  • Same here. 7.1.5 took down my network of over 30+ client sites. All 500 server error after updating.
    Thank god for backups

    Had my site crash after the latest update as well. Trying to locate the issue.

    same here.. Had to manually deactivate plugin to get site up again

    Rolling back to a previous version of Wordfence does not seem to work.

    Please take off this version as most sites are going to automatic updates….

    Don’t crash all my sites!!! Please remove this update!!!!

    Exactly the same here. Time to retire the 7.1.5 update if it’s breaking sites.

    Ok, I was able to use a server side restore to get back to version 7.1.4 and am stable. Anyone know what is causing the error?

    Thanks for doing something quickly before the automatic updates …

    Broke all the sites on my multisite too. I manually moved the wordfence folder out of the plugins folder, and the sites are working again.

    Deleted 7.1.5 file

    For now I just manually reinstalled 7.1.4 via FTP

    can download it at the bottom here:

    Will await fix for newer

    I am exceedingly angry at this plugin for being CRAPPY and taking down a site I don’t have FTP access to.


    It looks like they just released 7.1.6 – I assume/hope it addresses this issue.

    Hi all,

    The 7.1.6 release should prevent the issue on sites that have this error message.

    It occurs if your firewall configuration files in wp-content/wflogs/ cannot be read when the firewall loads. Normally, the plugin would only show a message on the Firewall page about being unable to read the files, but a recent change involved reading this data earlier. Sorry for the trouble.

    Even if installing 7.1.6 fixes the issue for your site, you should check the wp-content/wflogs/ directory (config.php in particular), to see if the permissions are incorrect, or if the files are owned by a different user — the firewall may not be fully working on your site in that case. (If you need help doing that part, please make a separate forum post, using the form at the bottom of the Wordfence support forum here: , per forum rules, and to make sure that your post doesn’t get mixed in while troubleshooting someone else’s.)

    Thanks for timely update @wfmattr
