When updating a premium plugin in WordPress, especially paid ones like The Plus Addons Pro, you may encounter the error message “Invalid License, Update Failed: Download failed. Unauthorized,” It usually indicates a problem with your license key. Here's a step-by-step guide to resolve it. ## How to Fix the "Invalid License Key" Error If you're 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're running the latest version of **The Plus Addons 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 - If your plugin is outdated and you're unable to update it due to the license error, you may need to **manually update** the plugin.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 [**POSIMYTH 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. **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're 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 i.e. 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's actually deactivated in this situation.  2. Your plugin license could have expired. If your license has expired and you try to update it, you'll 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 isn't active and you try to update the plugin, it won't work. 5. If your WordPress uses an old version of OpenSSL or cURL, the plugin might not update properly because it can't 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 **ThePlus Addons **> **Activate** **PRO**. - Click on the **Deactivate** button in the **Licence 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, you can check the [common license activation issues](https://theplusaddons.com/docs//how-to-activate-the-plus-addons-for-elementor/#Common-Licence-Activation-Issues). ### Manually Update You can manually update the plugin.

This can occur if the plugin was initially installed on a test site and later moved to a live site. Even if it shows as activated, it may not actually be valid for the current domain. Deactivating and reactivating the license from your WordPress site can often resolve this issue. **Q: How can I manually update The Plus Addons for Elementor if I can't activate my license?** A: To manually update The Plus Addons for Elementor, first download the latest version from the POSIMYTH Store. Then, deactivate and delete the existing plugin from your WordPress dashboard. After that, upload the new version and activate it. This method is useful if you're facing issues with automatic updates due to license errors. **Q: What are common reasons for the 'Invalid License' error when updating The Plus Addons for Elementor?** A: Common reasons for the 'Invalid License' error include domain mismatches, expired licenses, incorrect license keys, or inactive licenses. Additionally, if your WordPress setup uses an outdated version of OpenSSL or cURL, it may prevent proper communication with the licensing server, leading to this error. **Q: What steps should I take to ensure I'm using the latest version of The Plus Addons for Elementor?** A: To ensure you are using the latest version of The Plus Addons for Elementor, visit the [The Plus Addons Changelog](https://theplusaddons.com/docs//how-to-activate-the-plus-addons-for-elementor/#Common-Licence-Activation-Issues) to verify the latest available version. If your current version is outdated and you cannot update due to a license error, you may need to manually update the plugin. **Q: What should I do if my license key is correct but I still can't activate it?** A: If your license key is correct but activation fails, check for any server-side security rules that might be blocking the activation request. Sometimes, server firewalls can prevent outgoing connections to the licensing server, which is necessary for activation. Contact your hosting provider to ensure these connections are not blocked.
