Hi Sanne,
Thanks for reaching out.
I would suggest you update the X theme by following the below steps.
- Delete the Cornerstone version 4.2.3 which installed at your site
- Update the X theme to the latest version i.e. 8.3.3 on automatic updates
- After the X theme is updated, use the link in the dashboard to automatically install the Cornerstone. It will be at the latest version
If that does not helps, and the site crashed again. I would request you to please copy your live site to a staging server.
And give us access in the secure note including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
– FTP/CPanel credentials for file access
To create a secure note, click the key icon underneath any of your posts.
Thanks
