Hi There,
On The page where you assigned the website: https://community.theme.co/my-licenses/
Just beside the url you have a little grey x, click and assign the correct url.
Make sure you also have revoked the license from your wordpress installation in case you have assigned.
Here is the step by step:
1] Please go to X Addons > Home and revoke the validation.
2] Please login to your account and revoke the license. https://community.theme.co/my-account/
3] After you have revoke the license, you need to re assign the license again to your site using this url: https://www.your-domain.com/. You have to make sure that url you just assign is the same as the one you have in your settings, Settings > General > Site Address
4] Go back to X Addons > Home again, and insert the license again.
Hope it helps
Joao
