Visualforce page not displaying

I have a VF page that show data on my accounts page( that section links to accounts when loaded). There have been no changes and all of a sudden it doesn't show data anymore. I know the page is loading since the headers are present. What could cause this to stop working.

Its a bit difficult to tell without knowing what you are doing on your page.  Is it regular VF markup, are you using JavaScript to generate some content?

 

If you can post some code that would help.

This is something that was done by another developer. Why would something stop working that had no changes.

Its really difficult to say as we don't know what it does or how it does it.

 

As an example, if the contents of the page are all generated via JavaScript loaded from an external site and that moves, everything would suddenly stop working.  Or it could be a seemingly benign change to security or sharing that means the page can no longer find any data to display.
