Hi @charlie,
I apologise for posting this in the beta forum, but it is a particularly unusual issue.
I have a live eCommerce website which has strange problems. The Woocommerce Layouts (single and archive) are not accessible in Cornerstone, despite Woocomerce being active:
I have turned off all plugins (Woocommerce alone could not be deactivated) and the issue persisted.
The fact that the Cornerstone Layouts have disappeared is very worrying and I wonder if you can shed any light on this? I notice that Woocommerce is at 9.0.0, so wonder if there is a major update issue?
Many thanks,
Christopher
