#### Frequently Asked Questions

1. I have entered the correct key. However, it says the key is invalid

Make sure you do not have trailing or leading spaces. If your website is behind a firewall, make sure your firewall does not block the request and the response.

Also if you have a single-site license and trying to use it on multiple sites, then the validation will fail. A single-site license key is only valid for a single site.

{% hint style="warning" %}
**NOTE:** You can use the key in your local development environments (localhosts). That is not a problem.
{% endhint %}

2\. Still could not validate the key?
