Frequently asked questions
How do I know if my website uses TYPO3 8?
The checker looks for the generator meta tag, /typo3temp/ and /typo3conf/ assets and the fe_typo_user cookie. Recent TYPO3 versions hide their exact version.
Is it dangerous to keep using TYPO3 8 after support ends?
Without support, new vulnerabilities are not officially fixed, so the risk grows over time. It does not mean the site is compromised today.
How do I update TYPO3?
TYPO3 upgrades are done with Composer and the Install Tool; extensions and templates must be compatible with the target version.
