Resolving problems with license validation
When you install and activate WP Rocket, the validation of your license happens in the background.
If license validation does not happen automatically, you will see a screen like this:
It is not an issue that your license info is greyed out. You are not expected to edit these fields, they are automatically detected.
First, simply try clicking Save Changes. In many cases, that’s all that is needed. If that doesn’t help, move on to the next steps.
Check the Status Page
It’s there: https://wp-rocket.me/status/
Add our IP address to your Allowlist
Ask your web host to allow list this IP address:
Note: Adding this IP address to your allow list solves the issue in 99% of cases!
Our server needs to contact your site to do this. If your site is blocking external HTTP requests we will be unable to validate your license and you will see a message in your dashboard asking for your API key. Here's how you can resolve this.
Check your wp-config.php file and see if this line is present:
define( 'WP_HTTP_BLOCK_EXTERNAL', true );
If so, it is blocking the license validation.
This may be a good idea for security reasons, but it's better to allowlist approved hosts like us:
So you can delete the above constant, or set it to FALSE, and use the WP_ACCESSIBLE_HOSTS to allowlist us (and any other necessary domains via a comma separated list). For example:
define( 'WP_ACCESSIBLE_HOSTS', 'wp-rocket.me,*wp-rocket.me,*.wordpress.org,localhost' );
Deactivate security plugins
Some security plugins, depending on their settings, may also block the validation process. Please temporarily disable them while attempting to validate your license. Also, if you uninstalled a security plugin, please check your .htaccess file and clear any leftovers.
Download and reinstall
In rare cases, you may need to download WP Rocket from your account page, reinstall and activate it. Particularly if the validation screen shows an email address not associated with your account or generic license information.
An issue can occur if you have cloned your site from production to staging using a tool that performs domain replacements in your database. This can happen when you use the built-in staging features of managed hosts like WP Engine, Kinsta, Flywheel etc.
In these cases, if your WP Rocket account email is:
It will be updated on your staging site to:
Then it will no longer be recognized by our validation system. In such cases, you will see the incorrect email address on the WP Rocket Settings screen.
The solution is to define the correct license information in your wp-config.php file:
define( 'WP_ROCKET_EMAIL', 'INSERT CUSTOMER EMAIL'); define( 'WP_ROCKET_KEY', 'INSERT CUSTOMER API');
Replace "insert customer email" with the correct email associated with your WP Rocket account.
Replace "insert customer API" with the API key seen on the Settings screen:
After updating your wp-config file, visit WP Rocket's dashboard, and click the "Validate License" button. Your license should be validated.
If you are not able to see the API key and email on the settings screen, you can find this information in the
licence-data.php file, from the plugin ZIP file you downloaded from your WP Rocket account:

If you receive cURL error 60, this is related to an issue with the SSL certificate on your server. You should ask your host to resolve that error. To validate your WP Rocket license in the meantime:
- Install and activate the following helper plugin:

- Click “Save Changes” to re-try the license validation

If the helper plugin doesn't fix the issue, you can try the following (require root access to server):
