Im trying to install Projectpier, but I have run in to some problems.
I can get to the first page of the configuration (domain/public/install), but when I click the "Next" button I get this error:
Notice: date_default_timezone_set() [function.date-default-timezone-set]: Timezone ID 'gmt' is invalid in /var/www/public/install/include.php on line 17
Warning: Cannot modify header information - headers already sent by (output started at /var/www/public/install/include.php:17) in /var/www/environment/functions/general.php on line 323
The timezone-error is also on the first page of the configuration.
