I'm trying to install silverstripe, and I got this error date.timezone setting and validity!

What I've done :

in php.ini :
;date.timezone = America/Toronto

Didnt work, so I did too... in .htaccess, I've had this 2 lines on the top :
### set time zone ###
php_value data.timezone America/Toronto

And, nothing seem to work...

Hey, make sure to remove the ; character in front of the date.timezone in the php.ini - this is a comment character, if it's there php will be ignoring your config. Also ensure you are editing the correct php.ini file (sometimes there is a separate one for the command line use of PHP). To test, make a php file in your webroot, add the code.

<?php
phpinfo();

Save the file as something like "phpinfo.php" then visit in the browser, look for the "Loaded Configuration File" value which will tell you the correct config it's using (I've been caught out on this a couple of times... you live and learn).

Hope that helps :)

Thank you so much, everything work now!!!
