Re : blank page on install
Ok, i'll answer myself 😀
I manage to have it working, by commenting the line
include_once ('adodb-pear.inc.php');
in the file : **db/tiki-db.php**
The things i had to look at to (if you have same error) are the InstallTIkiUnderSafeMode page, as Damian said, the include_path of php (php.ini or, if you don't have acces, a .htaccess with line :php_value "include_path" ".:./lib:./lib/pear:/usr/local/lib/php"
;){kind=link}
