My store is running on PHP 7.4. Should I upgrade?
Yes, urgently. PHP 7.4 reached end-of-life in November 2022 and no longer receives security patches. You are running unpatched software with known vulnerabilities. Upgrade to at least PHP 8.1, ideally 8.2 or 8.3. Before upgrading: check that all your modules and your theme are compatible with the new PHP version. Test on a staging copy first. Most well-maintained modules support PHP 8.x already.
