Cornerstone error - The preview could not load, This is most often related to a plugin conflict or aggressive page cacheing

[amit3076]

I am using X theme with cornerstone as page builder. Some of my pages are giving this error when I edit it in cornerstone. I have seen few similar posts and followed along. Like this one - The preview could not load. This is most often related to a plugin conflict or aggressive page cacheing

I have done the following -

Everything including theme and plugins are updated.
I have tried disabling all third party plugins.
Add the following to wp-config.php -
set_time_limit(300);
define(‘WP_MEMORY_LIMIT’, ‘512M’);

Still I see this error. Page I am working on is this - https://www.igtsolutions.com/services/analytics/airline-analytics/

Any urgent help would be appreciated.

Thanks,
Amit

Hi Amit,

Thanks for reaching out.
There might be a few different reasons for this issue, I would suggest you troubleshoot the common issues related to it.

1.Plugin Conflict
2.Child Theme Related issue
3.CSS/JS Customization
4.Disabling Cache
6.Permalink

If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.

Hi,
Thanks for the quick reply!
I have already tested the plugins by deactivating all.
I also checked by activating the main theme.
I deleted the SG Optimizer plugin altogether to check the cache too.

I will share the admin details for you to check.

Hi Amit,

I have tried to open the page through the Cornerstone in all possible ways and it seems working fine, even I updated the page after modifying a small text, and that works too.
I tested it from X > Cornerstone, from Page List with Edit with Cornerstone and directly from the forntend X menu the Edit Page options.

Please check once by clearing your browser cache, or you can try it in Private or Incognito mode of the browser.

Thanks

This is strange! I tried it in firefox incognito mode, Also in chrome but same problem. Then I tried it on Microsoft Edge private window (which I never used before) and it worked.

Thanks anyways!

Hi Amit,

Glad it works finally. There might be something with cache in those browsers.

Thanks
