I just upgraded my server's PHP version to PHP 7.4.1 and now I'm getting this error:
Note: Trying to access array offset on value of type bool
public static function read($id) { $Row = MySQL::query("SELECT `Data` FROM `cb_sessions` WHERE `SessionID` = '$id'", TRUE); # http://php.net/manual/en/function.session-start.php#120589 //check to see if $session_data is null before returning (CRITICAL) if(is_null($Row['Data'])) { $session_data = ''; } else { $session_data = $Row['Data']; } return $session_data; } What is the fix for PHP 7.4?

If your query does not return a row, then your variable $Row will be filled with false, So you can test whether the variable has a value before trying to access any index inside the variable:
if($Row){ if(is_null($Row['Data'])) { $session_data = ''; }...Easy to use PHP
??Null coalescing operatorOr you can use
like this
