Hi there,
I am getting this error: “The preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing” when I try to edit my Home page with Cornerstone.
My site is www.soundpaintingsolutions.com.
Thanks in advance for any help.
Would you mind posting login credentials in a secure note? We can take a closer look at what’s going on?
Hi there,
same problem with our startpage.
On Subpages, its working?
The preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing.
Origin URL: https://ya-bielefeld.de
Preview URL: https://ya-bielefeld.de/
Browser: Chrome
Updated X from 1.2.3 to 1.2.4
Deactivated & Activated Cornerstone
Deactivated the caching plugin JCH Optimize.
See php errors
Update:
God, i don’t know. Today every page is working?
Just over the night. Nothing changed by myself! Is there any reason why? Does my X have feelings??? 
Just added – thank you in advance.
Same issue here. My thread: https://theme.co/apex/forum/t/cornerstone-error-a-conflict-on-front-end-of-your-site/14112/12
If you wait, the page loads behind the error message. I keep asking for them to add an [X] or [CLOSE] at the top right of the error message so I can dismiss it and work on my pages.
If I click “Try Again” it reloads the page, no error message, but everything that had previously loaded before disappears, and only the header and footer are displayed. Can’t edit the page.
The problem has persisted but now even worse, the Revolution slider and other basic functionalities from X Theme are gone, leaving me with a homepage that looks a lot worse it did before, despite me not making any edits to it. I can’t even attempt to fix it because Cornerstone editing doesn’t work. Really hoping to get some support soon.
Hello There,
Thanks for writing in! I have logged in to your site and when I edit a page I can see an error on the page. I am getting this
https://www.soundpaintingsolutions.com/cornerstone-endpoint 500 ()
https://www.soundpaintingsolutions.com/wp-admin/admin-ajax.php 404 ()
And it’s mostly related to security. Please contact your hosting provider and see if they can disable the security
Or exclude that URL and all requests (all payload related to that URL ) from your security rules.

Your login credentials is not working for us. It seems the password is incorrect. I would recommend that you open up your issue in another thread so that we can investigate and resolve the issue separately.
Thank you for your understanding.
Hello, my hosting provider let me know they could not find the errors you were referring to. They suggested that having Varnish exclude https://www.soundpaintingsolutions.com/cornerstone-endpoint might help and that I ask you for a custom VCL they can put in for that.
Thanks!
I am also still unable to edit my pages. I still get the error I referenced in the OP. I once was able to get it to work by refreshing, but generally I get that error or I get a condensed page where I cannot see any of the page content in order to edit (see below). Please advise… it’s been about a week now that I’ve been having issues. After having such a good experience with X Theme for so long this is frustrating. 
Hi There @soundpainting
Upon investigating this issue further, I see can see the following error messages on your console log.
Xfr request made by preview timed out
Nonce verification failed
Usually timed out should be related to your PHP max execution time. Try increasing it to the value 300.
Also please provide us with your FTP credentials to investigate this issue further.
Thanks!
Thank you! My max execution time is already set to 500. This was as of a few days ago when I reached out to my host for help. So anything else you are able to troubleshoot is much appreciated. FTP is in secure note above
I have the same challenge with a website I am currently working on. I have been working around resolving this issue in the last 48hours to no avail. I am a first time user of X theme and I am getting discouraged already. Kindly help me investigate and resolve it please.
It’s most likely just the cache.
@soundpainting, for troubleshooting purposes, please completely uninstall W3 Total Cache. See this article for guidance.
If that doesn’t help, please provide FTP access. I tried going to http://thedalles.dreamhost.com/ but it’s down.
@benpaul, if you’re using a caching plugin, please follow my advice previously. The article I linked to was for W3 Total Cache. If you’re using a different plugin, please contact their support to learn how to completely uninstall.
Please also try the following:
Ensure everything is up to date according to our version compatibility list at https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195. Please follow the best practices when updating your theme and plugins. See https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62 for more details.
Clear all caches including browser cache then deactivate your caching plugins and other optimization plugins.
If you’re using a CDN, please clear the CDN’s cache and disable optimization services.
Test for a plugin conflict. You can do this by deactivating all third party plugins, and seeing 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.
Remove custom CSS, Javascript and templates.
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.
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 nothing helps, please open a separate thread and give us WP Admin and FTP access in a Secure Note there because if you post here, the original poster could see it. Also post a link to this thread for reference.
Thanks.
Hello,
I’m having the same problem on one page of my website - my “purchase” page so the most important! Have tried everything I can think of but am quite new at this so must have missed something. Would someone mind taking a look at my website and helping me? It’s been like this for a week and I have reached my limit of experimenting 
The page is https://www.listenlightly.com/meditation-challenge/
Thank you!!
Lara
Hi Lara,
Please only add your credentials in a secure note in your own thread for security reasons 
But I checked and seems you already changed it, please start a new thread about this issue and we’ll be more happy to check it
Thanks!
I am having this same issue as well and here looking for answers!
It’s working now! It’s magic. Thank you!!
This fixed it for me, thanks! Possibly also pressing CTRL+R to reload the files instead of using cached versions could be useful.
@mbaez109 Please follow the solutions provided above, if nothing works, please create your own thread clarify the issue and provide us login credentials on a secure note.
@listenlightly You’re welcome, glad to hear that!
@rrhode Thank you for sharing, might as well purge all the caching plugins/features the site might have.
Have a great day,
Cheers!
Can you access it through here? https://webftp.dreamhost.com
I’m concerned with discontinuing use of W3 Total Cache. Since recently disabling it my site speed and ranking has noticeably fallen.
