Hi Gabriel,
Thank you for posting in! Do you have the latest version of the theme? To validate X properly, please do the following:
1] Please login to your account and assign the license (https://theme.co/apex/licenses). You need to assign the license to your site using this url: https://www.example.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
2] Go back to X > Validation, and insert the license code.
And please review the changes that we made on how you are going to validate your X theme because we made a big change in the process. Please check it out here: https://theme.co/apex/forum/t/setup-product-validation/55
If nothing is working, would you mind providing us the url of your site with login credentials so we can take a closer look?
To do this, you can create a secure note with the following info:
– Link to your site
– WordPress Admin username / password
To know how to create a secure note, please check this out: https://theme.co/apex/forum/t/how-to-get-support/288
Thank you.
