Cant get into cornerstone

[Jennine]

Hi,
I’m getting a Document Error: The response is not a valid JSON response when trying to open a page in the Cornerstone editor.

Please advise. The url is: https://lbylfilms.net/
Thank you!

Hello @Jennine,

Thanks for writing in! You do not seem to have a caching plugin or be using Cloudflare. This could be a plugin conflict or something. For further investigation, it would be helpful if you could provide the login information.

Cheers.

Can you please try to edit the top banner in the lighter blue color to this: LBYL FILMS SALES & DISTRIBUTIONS to attend the 76th Berlin International Film Festival (Berlinale) in Germany, February 12–22, 2026. If I get into the backend and try to save my edit, I get this error
