"A conflict on the front end of your site has prevented the preview from loading." - Have tried all the usual steps

We have getting this error: “A conflict on the front end of your site has prevented the preview from loading.” We have tried clearing cache, disabling all plugins, turned off our CDN tried new browsers. We are even getting it with all plugins disabled except cornerstone. No joy. Any help would be appreciated.

Hi there,

Kindly try to make sure that you have updated the URLs on your site and have the none https link updated.

In case the issue persists, please provide us with the admin and FTP access to your site in a secure note.

Secure note sent. Please take a look if you can. Thanks!

Hi there,

Thanks for writing in.

It’s due to HTTPS, the preview is loaded in HTTP and it’s not allowed by the browser. There are other threads with the similar issue and they are all hosted in WPEngine just like yours. Looks like sites has internal issues when switching to HTTPS?

Would you mind contacting WPEngine and see if they can fix the HTTP/HTTPS related issue?

Thanks!

We found where we were forcing HTTPs in a subsetting in WPEngine under the domains in their SSL tab in their control panel. Once disabling that it works. Thanks for clarifying this for us.

Thanks for letting us know!
