Overview Most WordPress failures are preventable. This lesson introduces a set of routine practices that reduce the likelihood of common errors—500s, WSOD, database failures, and lockouts—by maintaining site health proactively. The goal is to minimize emergencies and ensure recovery is fast and reliable when issues do occur.
Why Preventative Troubleshooting Matters Troubleshooting is easier when the site is stable, backed up, and documented. Preventative routines reduce the risk of outages and make recovery faster and safer. They also improve performance and security, reinforcing trust and uptime.
Core Preventative Practices
- Update Discipline
- Always test updates in a staging environment before deploying to production
- Enable auto-updates for minor and security patches
- Review changelogs before applying major releases
- Use version control or snapshot tools to roll back if needed
- Backup Strategy
- Daily database backups
- Weekly full site backups (files + database)
- Store backups offsite (cloud storage or dedicated backup service)
- Test restoration procedures quarterly to ensure integrity
- Database Optimization
- Remove post revisions, spam comments, expired transients
- Optimize tables monthly using WP-CLI

- Monitor database size and query performance using Site Health and hosting tools
- Access Hardening
- Enforce strong passwords and two-factor authentication for all admin accounts
- Apply least-privilege roles—only give users the access they need
- Monitor file integrity using the Sucuri plugin or equivalent
- Restrict access to wp-config.php and sensitive directories via .htaccess or server rules
