Setting up your server
There are different settings you may set up within your server to improve the performance, the maximum filesize upload limit, how to send the email notifications, etc.
Changing the Maximum Filesize upload limit
There are two files you may have to change for this, other than the Apache server settings by allowing overrides.
In the example below, it will limit the maximum filesize to 100 MB. Use another value if you want to of course.
Access (or create if it does not exist) the file named FENG_ROOT/.htaccess and add the following lines:
php_value post_max_size 100M
php_value upload_max_filesize 100M
Then, access (or create) the FENG_ROOT/php.ini file and add the following lines:
post_max_size = 100M
upload_max_filesize = 100M
