Cannot enter Cornerstone Editor


I used to use cornerstone to edit all the pages on my client’s website while creating it. Since finishing it, a few months have passed, and my client is now wishing to use cornerstone to make small edits on pages. However, when cornerstone is selected, I am unable to enter into the actual editor.

A menu page to select a page is opened with options to open the editor on each page, but the ‘edit’ buttons do not take you anywhere. Why does this happen? How can I open cornerstone to make changes to existing pages? Below is as far as I’ve been able to get.

Hello @GeoffreyPearson,

Thanks for asking. :slight_smile:

Please follow up the steps below:

  1. Ensure everything is up to date according to our version compatibility list here. Please follow the best practices when updating your theme and plugins. Click here for more information.
  2. Go to X > Settings and click on the Clear Style Cache button.
  3. If you’re using a CDN, please clear the CDN’s cache and disable optimization services.
  4. Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
  5. Remove custom CSS and Javascript from the options or Child Theme and test the case.
  6. 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.
  7. Increase the PHP Memory Limit of your server. Click here for more detailed information and how to increase the PHP memory limit.

If you still have problems kindly get back to us with the result of the steps above and URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case.

Thank you.


I did my best to use the above solutions to fix the issue, but with no avail. Attached is a secure note with the information you requested.

Please let me know if anything can be done.

Thank you!

Hi There,

Thanks for the details!

I checked your site and seems you are facing cs-vendor.js loading issue. which is required to run cornerstone.

Contact your host to increase your allocated memory or do it yourself by adding this code in your wp-config.php

define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

If that doesn’t help please delete theme and cornerstone and re-upload a fresh copy of the theme.

Let us know if that works.

Thank you, that fixed the issue!

You’re welcome.

HI There,

Thanks for writing in!

We would encourage you to please create a new post and give us the details on a secure note so that we can check your issue. I am going to delete your post here as this is not your original post and anyone can view your details.
