AEM Author Page Displays Grey/Blank Screen in Edit Mode

Hi Community,

I am experiencing an issue where a page in the AEM Author environment displays a grey/blank screen when opened in Edit mode. The page is accessible on the published environment and appears to function as expected there.

We are trying to understand the possible causes and recommended troubleshooting approaches for this type of behavior.

A few questions:

1. What are the common reasons an AEM page might display a grey/blank screen in Author while working correctly on Publish?
2. Are there specific logs, tools, or debugging techniques you typically use to identify the root cause?
3. Have you encountered situations where page components or page content caused Author rendering issues?
4. What is the best approach to isolate the problematic component or configuration when the page itself cannot be opened normally in the editor?

Any suggestions, best practices, or experiences would be greatly appreciated.
 

Thank you.
