Is this happening on all pages or just one?

I have seen this error on all pages when the instance is running behind a proxy and the proxy is blocking certain IPs.

If it is just a single page there might be something on the page that is causing the page to fail as it has been corrupted.  I would suggest creating a new page and carefully coping content from the old page to the new page to try and identify what is corrupted on the page.
