* **Data base configuration**: If the installer asks you for charset, select the appropriate character set, e.g. [cp1252 Western European] for Latin 1.
===Captcha===
To use Captcha, you must ensure that the session settings in **freecap.php** do not differ from the default values or your config settings,
else Captcha can't pass its values to the session. In the following link you find a workaround for this from our Development-Blog:
