error during installation 1.5.5.1

Hello,

there is someone out there who knows what the problem is and how to fix it.
During installation I get the following error message:


Deprecated: mysql_connect (): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /customers/3/4/4/luststugan.se/httpd.www/system/database/mysql.php on line 6 Warning: Can not modify header information - headers Already late by (output started at /customers/3/4/4/luststugan.se/httpd.www/system/database/mysql.php:6) in / customers / 3 / 4/4 / luststugan.se / httpd.www / system / engine / Controller.php on line 28 Warning: Can not modify header information - headers Already late by (output started at /customers/3/4/4/luststugan.se/ httpd.www / systems / database / mysql.php: 6) in /customers/3/4/4/luststugan.se/httpd.www/system/engine/controller.php on line 29

Thanks in advance!

Just search for this in Google:

in order to find many answers on this!

Why are you installing 1.5.5.1? If you don't want to use the 2.x version (which I would recomend), atleast use 1.5.6.4.
