What's going wrong
Site owners on shared hosts and older PHP versions report that Contact Form 7 version 6.2 and later raises its minimum PHP requirement to 8.3, so updates are blocked or the site crashes. Some sites show a critical error, a composer platform check fatal error, or a blank page even when they were not updating, and others on PHP 8.4 or 8.5 still see the requirement warning on network child sites. Owners running Google Sheets connectors and managed hosts say they lack staging environments and want a safe way to test and recover. Agencies and small businesses that rely on contact forms are most affected.
