It works this far, then i don't know what the wrong is. Can anybody help me out with this. Can provide the most information you need.

Does your server support mod_rewrite? Try to put it to false in zp-config.php.

zp-config.php:
LINE 48 $conf['mod_rewrite'] = true;

to

LINE 48 $conf['mod_rewrite'] = false;
