Automatic Update

Wordfence has its own “Automatic Update” function. If you enable this, new versions of Wordfence will automatically be installed on your site.

If your site is hosted on a LiteSpeed web server, please read the help page about configuring LiteSpeed to ensure that the automatic updates of your Wordfence plugin complete without any problems.

In very rare cases, allowing Wordfence to update automatically can be problematic because the update may fail and you won’t know about it until you login to your site and see that Wordfence is missing from the list of plugins for example. This can also happen to other plugins that have a feature to update automatically and not just Wordfence. Often site owners will try to install Wordfence again and be presented with a common error message containing, ‘Destination folder already exists’.

An automatic update of Wordfence is usually related to a problem on the hosting server. The update process involves removing old files, extracting the new plugin and then copying over the new files to the plugin location. On some hosting servers that process can exceed the PHP max_execution_time or even the gateway timeout. It is usually during the last part of the transfer when the new files are copied over that issues can occur.

To resolve this you can manually delete the Wordfence plugin directory in the plugins directory below:

~/wp-content/plugins/wordfence

All of your plugin settings will remain intact as they are stored in the database.

You can then reinstall the plugin again on the WordPress Plugins page.
