cleaner.php - Parse error: syntax error

Hi @AlexSheer,

on a local environment (PHP 7.2.x | phpBB 3.2.8 fresh install) I try to access to the ./stk/cleaner.php file but I encounter this error:

```
Parse error: syntax error, unexpected '$stk_passwd' (T_VARIABLE), expecting identifier (T_STRING) in C:\UwAmp\www\quickinstall\boards\phpbb328fr\stk\cleaner.php on line 289

```

What’s this issue?
