If you’ve ever run into a white screen while trying to edit a post or page in WordPress, you know how frustrating it can be — especially when it happens on a live site. I recently faced this exact issue on a WordPress website hosted on Cloudways, and here’s how I identified and fixed it, I am an expert in WordPress Customization so this was easy to solve with a little bit of help from internet.
The Problem
One day, I logged into the WordPress admin area of a live website and tried to edit a post. But instead of loading the content editor, the screen was completely blank — no errors, just a white screen. This issue persisted across multiple posts and pages, making content management impossible.
Initial Troubleshooting
To avoid disrupting the live environment while investigating the problem, I cloned the site to a staging environment on Cloudways. To my surprise, the white screen issue didn’t occur on the staging site.
At this point, I knew the issue wasn’t related to the WordPress core, the theme, or the plugins, because the staging site was an exact replica of the live one. That led me to believe the problem had to be something external.
The Clue
Digging deeper, I checked the Cloudways error log and saw a message that hinted at the issue:
“cache full”
That was my first real lead. I tried clearing the cache using the WordPress caching plugin installed on the site, but it didn’t solve the problem.
The Real Fix
Then I remembered a key difference between the two environments:
The live site was using Cloudflare, while the staging site was not.
So I went into the Cloudflare dashboard and purged the cache.
Immediately after clearing the Cloudflare cache, the white screen issue disappeared on the live site. The editor pages began loading normally again, and everything was back to business as usual.
Takeaway
If you’re seeing a blank screen when editing posts or pages in WordPress and everything seems fine otherwise, Cloudflare cache could be the culprit — especially if your staging site works but your live site doesn’t.
