Redirection to the validation page is normal after activating whether the parent theme or the child theme.
What is not normal is your child theme is not activated after that. I checked your site though and I see the child theme is already active. If you don’t see that in your backend or WordPress Admin, your server’s cache might be very aggressive. In that case, you’ll need to contact your web host to learn how to clear all caches in your server. Clear your browser’s cache as well.
Hi, OK thank you. I’ll contact them and see, if they have a solution.
After I installed and (apparently) activated the child theme, I’m not able to choose between the Demos. I thougt it was due to the child theme not beeing active. But since it IS active, shouldn’t I then be able to choose a demo and start working?
Or is this error also due to the cache’s need of beeing cleared?
Kindly check the version of your X and Cornerstone and make sure that both of them are updated to the latest version.
In case the issue persists, please provide us with the admin access to your site in a Secure Note:
