Cornerstone not working since the last update


As you asked I created a new topic.

Cornerstone, it doesn’t seem to want to work in wordpress neither will it update. I keep getting the error: “The preview could not load. This is most often related to a plugin conflict or aggressive page cacheing”.

I update to PHP 7 but it still doesn’t work :confused:

Hi There,

Thanks for writing in!

As I do not have access to your website dashboard I will suggest few troubleshooting steps that you should follow:

  1. If you’re using a CDN, please clear the CDN’s cache and disable optimization services. For the CloudFlare please follow the steps below:
  2. Remove custom CSS and Javascript from the options or Child Theme and test the case.
  3. Reset your htaccess file by renaming it to .htaccess-bak. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button.
  4. Follow the steps mentioned here.
    A very important point Please see if you are using cornerstone and theme both latest version.

If that doesn’t help please send us your website details so that we can have a look.

Please provide following information:
Set it as Secure Note

  • Link to your site
  • WordPress Admin username / password
  • FTP credentials
    All the best!

Thank you.

How can I give you access to my web site ? :slight_smile:

Hey Céline,

Yes, please give us WordPress admin and FTP access in a Secure Note.



It was the w3 total cache plugin that was causing the issue.

I deactivated the plugin and Cornerstone is working fine now.

If you would like to use that plugin, you will need to exclude the theme js files from minification
