When updating a premium plugin in WordPress, especially paid ones like The Plus Addons for Elementor Pro, you may encounter the error message “Invalid License, Update Failed: Download failed. Unauthorized.” It usually indicates a problem with your license key. Here is a step-by-step guide to resolve it. ## How to Fix the “Invalid License Key” Error If you are trying to activate your license key and encounter the **“Invalid License Key”** error, follow the steps below to troubleshoot and resolve the issue: ### 1. Ensure You’re Using the Latest Plugin Version Before proceeding, confirm that you are running the latest version of **The Plus Addons for Elementor Pro**. **To check and update your version:** - Visit** [The Plus Addons Changelog](https://roadmap.theplusaddons.com/updates)** to verify the latest available version. - If your plugin is outdated and you are unable to update it due to the license error, you may need to **manually update** the plugin. ### 2. Check and Re-Activate Your License Key Sometimes the error may occur due to a domain mismatch or old license records. **To resolve this:** - Go to your [**The Plus Addons Store Dashboard**](https://store.posimyth.com/)**.** - Locate your license key under the relevant product. - Click on the **“Manage Site”** button (above the license key). - **Deactivate** the domain currently using the license (if listed). - Return to your WordPress site and re-enter the license key to activate it again. ### 3. Check Your Server-Side Firewall and Security Rules Sometimes, the license validation or update request from your WordPress site can be blocked by your server’s firewall or security system. If the server firewall is blocking outgoing connections to the licensing updater server, you might see the error when trying to activate the license key. For a related access issue, see [Fixing “Unauthorized Access” or Missing Content Error for Specific Widgets](https://theplusaddons.com/docs/fixing-unauthorized-access-or-missing-content-error-for-specific-widgets/). **To fix this**: - Ask your hosting provider or server admin to ensure that outgoing connections (especially to the licensing server) are allowed and not blocked by firewalls, mod_security rules, or other server-side security tools. If you are still encountering the error after following the steps above, it could be due to one of the following common reasons: ## Reasons 1. There could be a domain mismatch, meaning the website from which you are trying to update the plugin is not connected with the plugin license. This can happen if you first install the plugin on a test site and then move it to the real site using the same license. Even though it might say the license is “**Activated**,” it is actually deactivated in this situation. 2. Your plugin license could have expired. If your license has expired and you try to update it, you will see this message. 3. You might have entered the wrong license key for the plugin, which will prevent the plugin from updating. 4. Your plugin license might be inactive. If your license key is not active and you try to update the plugin, it will not work. 5. If your WordPress uses an old version of OpenSSL or cURL, the plugin might not update properly because it cannot securely communicate with its server. ## Solution ### Deactivate and Re-activate License Deactivate and reactivate the plugin license from your WordPress website. This will fix the domain mismatch issue. For The Plus Addons for Elementor plugin, follow the steps. - From the Dashboard, go to **The Plus Addons for Elementor** > **Activate Pro**. - Click on the **Deactivate** button in the **License Activation** section. - Then paste the license key again and click on the **Activate** button. ![](https://theplusaddons.com/wp-content/uploads/2024/03/the-plus-addons-elementor-activate-deactivate.gif) If you are having any issues while activating the license, see [How to Install & Activate The Plus Addons for Elementor PRO?](https://theplusaddons.com/docs/how-to-activate-the-plus-addons-for-elementor/#Common-Licence-Activation-Issues) for common license activation troubleshooting steps. ### Manually Update You can manually update the plugin.
