Cornerstone preview was unresponsive

[robsenzon]

I am unable to get cornerstone to load.

I recently migrated to a new host. Seems I can only get cornerstone to load on pages that don’t contain a rev slider.

This is the error i get. I get it on production and staging (staging has no cache)
The preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing.

Origin URL: https://www.foodincnyc.com
Preview URL: https://www.foodincnyc.com/about/

I also see this in console
[Error] Failed to load resource: the server responded with a status of 404 () (huebert.js.map, line 0)
[Error] Failed to load resource: the server responded with a status of 404 () (cs-head.js.map, line 0)
[Error] Failed to load resource: the server responded with a status of 404 () (x.js.map, line 0)
[Error] Failed to load resource: the server responded with a status of 404 () (cs-body.js.map, line 0)

I have tried upgrading and downgrading cornerstone and rev slider.
I have tried rebuilding .htacess

really t the end of my rope. I have used cornerstone for years without issue. This must be a product of the migration?

Hello @robsenzon,

Thanks for asking.

I am sorry for the trouble you are facing but it seems that the problem is coming because of migration issues. Please do following:

1. Deactivate and delete Cornerstone, X Theme and Revslider and reinstall all of them. See if you are able to edit pages that has Revslider.
2. In case re-installation don’t works out then you need to migrate the website again. You can use plugins like All-in-One WP Migration. https://wordpress.org/plugins/all-in-one-wp-migration/. Here’s a getting started guide that you can take a look.

Thanks.

I reinstalled to no avail.

My comment about rev slider was incorrect. I created a new page, added a rev slider, saved it, exited, then was able to edit the page with no problem. So its not a rev slider issue.
It seems it only existing pages. New pages can be created and edited with no problem. Is it something in the database with the old content?

Ihave deactivated all plugs as well with no luck. Happy to provide a login. I can not figure out why im getting the caching error message when no cache exists.

I am still seeing the following in my console.

[Error] Failed to load resource: the server responded with a status of 404 () (cs-body.js.map, line 0)
[Error] Failed to load resource: the server responded with a status of 404 () (cs-head.js.map, line 0)

Hi There @robsenzon

Source map are not related to any of these issues. It’s use for debugging so please ignore it, unless you’ll debug it which is you can’t do since it’s limited to our developers only. You can refer for more information https://developers.google.com/web/tools/chrome-devtools/javascript/source-maps (Enable Source Maps in settings, from same setting, you can disable it).

One of the most common issue related to preview unresponsive is PHP memory limit. Could you please try increasing your PHP memory limit by following our guide here (https://theme.co/apex/forum/t/troubleshooting-increasing-php-memory-limit/16935). Also check the PHP version running on your server and make sure to use PHP v5.6.x or later to avoid incompatibility issue.

If you’re still having issues, please provide us with your WordPress login credentials in a secure note to investigate your issue further.

Thanks!

Secure note left. I tried all of the above with no luck.

Hello @robsenzon,

Thanks for asking.

Yes, Cornerstone is working on the new pages but there’s issue over there too. On left side panel I don’t see couple of icons and in dev tools I see error message as shown in screenshot.

Both in existing pages and on new pages I see that resources are being served from different URL. Website is hosted on http://foodincprod.staging.wpengine.com/ but resources are being called from http://foodincprod.wpengine.com. I suggest you to migrate the website again using plugin like All-in-One WP Migration as couple of functionality like preview button icons is also not showing up and might be there’s a case of coupoupt migration.

Let us know how it goes.

Thanks.

Would you try my production URL. Do you see the mixed URLs there as well?

Hello There,

I am seeing the same in both the staging and live production site. I can edit your homepage without any issues (https://prnt.sc/kof5c8). The other pages were unsuccessful as I could not edit it. I am encountering this error in the console:

The preview booted, but never requested the loader be removed

Could you please try increasing your PHP max script execution time to 300 and test again to see if that helps. Also try deleting Cornerstone plugin and re-install it again by head over to X -> Validation section (wait for few seconds to install it automatically).

And by the way, please make sure that your server has meet the requirements in running the latest WordPress.

Please let us know how it goes.
