TLDR: The WordPress White Screen of Death (WSoD) halts website functionality, necessitating diagnosis via methods like disabling plugins, switching themes, clearing cache, or increasing PHP memory limits. 71% of companies faced downtime in 2021, costing $5,600 per minute. Key solutions include enabling debug mode, increasing memory limits, deactivating plugins/themes, clearing caches, addressing auto-update errors, checking for code errors, and restoring backups. Best prevention strategies involve using staging environments, maintaining regular backups, employing error monitoring tools, and ensuring proper access control. Structured development practices via tools like Advanced Custom Fields (ACF) enhance stability and reduce WSoD occurrences.
