Invalid License Key
If you have added your license key but you’re getting an error message saying “This license is not valid”, try these steps to troubleshoot:
- Firstly, double check that the license key is correct.
- Next, try deleting the license key and clicking Save Changes. Then re-enter the license key and click Save & Re-check All Licenses.
- If you’re still getting an error, you can use a little plugin called Charitable License Tester, which can be downloaded from: https://www.dropbox.com/s/6zm7n0l7zsrmez2/charitable-license-tester.zip?dl=0. After you install it, just go to https://your-site.com/?charitable-license-tester. You’ll see a form where you can enter your license key. That will provide a whole bunch of information about the request taking place between your site and ours. Please send us the link once you have set it up and entered your license key.
