WordPress white screen: a safe troubleshooting process
Recover from a blank WordPress page using scoped checks, recovery access and protected logs. Isolate recent changes before replacing files or restoring data.
Before changing production
Preserve a complete backup and a way to recover through hosting access. Use staging for component isolation when possible. Record the exact symptom, affected URL, time and recent changes before disabling anything.
If the site handles orders or submissions, a restore can overwrite newer records. Ask the host how to preserve that data. Stop when a file or server change is outside your understanding; giving the host a clear reproduction is useful progress.
