How to fix "An error occurred, please try again." when trying to activate your product key ?

When trying to activate your product key for a theme or a plugin, you might get the following error message : "An error occurred, please try again.".

In most of the cases, it's due to a wrong key. Like for example a missing character.

Here are the steps to fix the problem :

1. Make sure you copy the correct activation key ( Where can you find your activation key ? ) Sometimes there can be a missing character at the beginning or at the end for example.
2. Paste the correct key in the activation key field
3. Click on the Save Changes button
4. Click on Activate Key

If this still doesn't work, you can try again later. It might be a temporary connection issue with our server. Or a temporary issue with your server, blocking remote requests.

Note that the activation of the key allows you to be notified in your WordPress admin for a new version of your product. If you don't activate, it won't prevent the theme or the plugin to work fine.

You can always download the latest version of the theme from your account as documented here.
