Hello,
I was previously using wordfence security plugin but later on I deleted. In file manager there was a file name wordfence and I removed it as I thought I don’t have this plugin now. After that my site is down. This is quite frustrating for me. Kindly help to solve the issue.
I am getting this error in error_log.
PHP Fatal error: Unknown: Failed opening required ‘/home/channeli/public_html/therecipespk.com/wordfence-waf.php’ (include_path=’.:/opt/alt/php54/usr/share/pear:/opt/alt/php54/usr/share/php’) in Unknown on line 0

Just disconnect it in .user.ini, .htaccess, or php.ini, wherever the auto_prepend config was put.

Should have been done before deleting the file.

Hi ambersaleem!
As already mentioned, some code has been left behind in your .htaccess file and/or a .user.ini file which loads the file you deleted via a PHP value called auto_prepend_file. Please check those two files, they will be located in the root of your WordPress installation (where you found and deleted the wordfence-waf.php) file. Remove any code from them that sets auto_prepend_file. Here is an example of what that code can look like

php_value auto_prepend_file '/home/public_html/wordfence-waf.php'

Best of luck for now!

Hello,
I just upgraded my WF account to Premium. When trying to enable the Firewall I get the message “unable to write to ~/wp-content/wflogs/ which the WAF uses for storage. Please update permissions on the parent directory so the web server can write to it.” Couldn’t find any file named wordfence-waf.php. Am I creating a new one? Confused????

My web server doesn’t allow writing to wp-content/wflogs. Your fix on https://docs.wordfence.com/en/Wordfence_constants_for_advanced_configuration says I should add this line:
define(“WFWAF_LOG_PATH”, ‘/var/www/html/wp-content/wflogs/’);after the opening.

I’m not sure of the proper syntax for adding this line. I get an internal server error when adding it.

Where and whats the proper syntax, please
Here’s my file .htaccess file:

DirectoryIndex index.php

# BEGIN WordPress

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Thanks
JD

Hi juciydesigners!
The docs you referenced can be used to set a different path to wflogs than the default path. Normally Wordfence tries to store the Firewall configuration files in wp-contet/wflogs but if you want it to use a different directory, you can use the WFWAF_LOG_PATH constant to set that. The directory should be a directory that is writable by the user that WordPress is running as. You do not need to create the directory, but it must be in a location that is writable. Hope that makes sense!

If you have Wordfence premium you’ll get quicker response if you send in a ticket via support.wordfence.com
