Still can't validate X

I’m still having problems validating X on one of my websites.

I’d previously provided the url and login credentials, and you asked me to make sure I’m running up to date versions of X and Cornerstone, but this hasn’t worked.

I have a valid purchase code, I can enter it in the text field, but hitting enter has no effect.

Please help!

Hello There,

Thanks for writing in! I have logged in and tested validation in your site. I can confirmed that the issue is happening on the site. Further investigation showed that you are using an older version of X and Cornerstone. You will have to update the X and Cornerstone manually. Please download the latest files from your dashboard (https://theme.co/apex/dashboard) and upload it to your ftp. For more details about how you can update X and other plugins manually, please check this out: https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62

Please let us know how it goes.
