- includes/db.php: shared mysqli connection + parameterized query helpers (pqs_db/pqs_exec/pqs_rows/pqs_row/pqs_val), targets PHP 7.4+. - Replace 11 mysql_error() calls (undefined function on PHP 7+) with mysqli_error($link) / mysqli_connect_error() across getFSgame, getFSplayers, config, callsign, console. Only affected already-failed error paths. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
