After AChecker is configured, delete this top-level index.php file. The lock file prevents accidental reinstallation.
Use a separate database, HTTPS, and an empty subdomain directory. This installer downloads the official AChecker source and its required Plates dependency. It also applies the required PHP 8 compatibility repair, stores every installation step and PHP failure in install.log, and can repair an existing installation in place. Diagnostics are built into this same page.
