I just did an upgrade to 4.4.1 but now my site does not look like it supposed to be. I see I got Cornerstone 1.2.3, but deactivating does not help. The X-Child theme that is active is Renew.
I have only official X related plugins activated, so I cannot find the reason.
Thanks for writing in! Kindly activate your parent theme and check again. If you see the issue is solved then you need to update your Child Theme. Kindly follow this for the solution – https://community.theme.co/forums/topic/child-theme-updates/
