I'm trying to install SilverStripe on my Webspace. When I'm opening the install.php, the following errors appear:
Warning: session_start(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/home/www/xxx/html:/home/www/xxx/phptmp:/home/www/xxx/files:/home/www/xxx/atd:/srv/www/htdocs/xxx/html:/srv/www/htdocs/xxx/phptmp:/srv/www/htdocs/xxx/files:/home/www/xxx/atd) in /home/www/xxx/html/SilverStripe/install.php on line 10 Fatal error: session_start(): Failed to initialize storage module: files (path: ) in /home/www/xxx/html/SilverStripe/install.php on line 10
Strange. What version of PHP do you have? There are some reports on a bug in PHP that has this behavior, but if you are on a webhost, there should be no problems with session_start() as it is probably used by almost all PHP scripts.
Do you have a phpinfo file (a xxx.php file with only <? phpinfo(); ?> in it) on that server, that can be checked?
