WP 5.1 Edit/New post/page shows blank white screen

Question

After updating to WordPress 5.1, when I Add/Edit a page/post, the screen is white (blank). I had tried without success:

1. Disabling other plugins and themes
2. Clearing the Browser cache
3. Trying a different Browsers and Computers (including mobile)
4. All plugins and themes are up to date
5. Reinstalled 5.1
6. I've also installed Health Check Troubleshooting.

Any help resolving the issue would be much appreciated. Thank you.

Answer 1

You should activate debug logging by setting

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);

in wp-config.php

After doing this, re-try your attempt of adding/editing a post and then visit the debug.log in /wp-content folder. Post the entries here that match the point in time and one can narrow the issue further down.
