- In your Drupal site, go to admin/settings/uploads
- Raise upload limits. If the value you want to insert is greater than PHP allowed value:
- On bottom of your .htaccess file (drupal/.htaccess) add these lines:
# upload settings
# cfr. http://it.php.net/manual/it/function.ini-set.php
php_value post_max_size 50M
php_value upload_max_filesize 50M
php_value memory_limit 128M
Change values as you wish. - Return to admin/settings/uploads and watch changes on PHP limit.
