Introduction to TYPO3 Website Maintenance
TYPO3 is a powerful, enterprise-grade content management system used by organizations worldwide. Like any website, TYPO3 installations require regular checks and maintenance to ensure optimal performance, security, and user experience. This article will guide you through the essential steps for conducting a thorough TYPO3 website check.
1. System Requirements Check
Before diving into content and functionality, verify your server meets TYPO3’s requirements:
- PHP version compatibility (check TYPO3’s documentation for your version)
- Database requirements (MySQL, PostgreSQL, etc.)
- Server resources (memory_limit, max_execution_time)
- PHP extensions (GDlib, Fileinfo, OpenSSL, etc.)
Use the TYPO3 System Environment module (Admin Tools > Environment) to identify any missing requirements.
2. Core and Extension Updates
Outdated software is the leading cause of security vulnerabilities:
- Check for available TYPO3 core updates
- Review all installed extensions for updates
- Remove any unused extensions to reduce attack surface
- Verify extension compatibility with your TYPO3 version
3. Security Audit
Critical security checks include:
- User and access management review
- File permissions (especially in fileadmin and typo3conf)
- .htaccess protection for sensitive directories
- Check for known vulnerabilities in your TYPO3 version/extensions
- SSL certificate validity and configuration
- Cross-site scripting (XSS) and SQL injection vulnerabilities
4. Performance Evaluation
Assess your website’s speed and efficiency:
- Frontend performance (use tools like Google PageSpeed Insights)
- Backend performance (check slow backend operations)
- Caching configuration review
- Image optimization status
- Database performance (look for slow queries)
5. Content and SEO Review
Content-related checks:
- Broken links (internal and external)
- Metadata completeness (page titles, descriptions)
- XML sitemap generation and submission
- Canonical URLs implementation
- Duplicate content issues
- Language handling for multilingual sites
6. Backup Verification
Ensure your backup strategy is robust:
- Database backups frequency and integrity
- File storage backups (fileadmin, uploads)
- Backup restoration procedure testing
- Off-site backup availability
7. Upgrade Preparation
If planning an upgrade:
- Review deprecation logs for needed changes
- Test upgrade in a staging environment first
- Prepare rollback plan in case of issues
- Document all customizations that might need adjustment

Conclusion
Regular TYPO3 website checks are essential for maintaining a secure, high-performing website. By following this comprehensive checklist, you can identify potential issues before they affect your users and ensure your TYPO3 installation remains stable and efficient.
For complex environments, consider engaging TYPO3 professionals to perform in-depth audits and optimization. Remember that prevention is always better than crisis management when it comes to website maintenance.
