How to unlock unlimited premium Wordfence Security license on any version

advertise here
  1. Download the official Wordfence security plugin from: https://en-ca.wordpress.org/plugins/wordfence/
  2. Upload the plugin to your wordpress but don't activate it
  3. Next, in your wordpress main dashboard head to Plugins -> Plugin Editor
  4. In the "Select plugin to edit" bar choose Wordfence Security and press Select
  5. Under the "lib file section" select the wordfenceClass.php file
  6. Press ctrl+f and paste this:
if (!WFWAF_SUBDIRECTORY_INSTALL && $waf = wfWAF::getInstance()) {

You should see:

$updateCountries = false;
if (!WFWAF_SUBDIRECTORY_INSTALL && $waf = wfWAF::getInstance()) {
$homeurl = wfUtils::wpHomeURL();

$siteurl = wfUtils::wpSiteURL();


Now right under it paste this in:

wfConfig::set('isPaid', 1);
wfConfig::set('keyType', wfAPI::KEY_TYPE_PAID_CURRENT);
wfConfig::set('premiumNextRenew', time()+31536000);

So the code should look like this:

$updateCountries = false;
if (!WFWAF_SUBDIRECTORY_INSTALL && $waf = wfWAF::getInstance()) {
$homeurl = wfUtils::wpHomeURL();
$siteurl = wfUtils::wpSiteURL();


wfConfig::set('isPaid', 1);
wfConfig::set('keyType', wfAPI::KEY_TYPE_PAID_CURRENT);

wfConfig::set('premiumNextRenew', time()+31536000);

7. Save the file, then activate WordFence plugin, you should have unlimited premium license! It says "renew in 365 days" but you will notice that this number doesn't go down ;)
