FILE upload sizes are restricted in a number of ways – each one in the list restricts the following ones.

• Firstly, there is a setting in Apache 2 which you may need to change. On Redhat this setting is very low by default, you can change the limit by adding or editing a line in Apache’s

/etc/httpd/conf/httpd.conf and/or /etc/httpd/conf.d/php.conf with the upload size in bytes (different operating systems may have these files in different locations):
LimitRequestBody 10485760 

• PHP also has two more byte limits, which you can set in php.ini and SOMETIMES in a .htaccess file:

php_value upload_max_filesize 50000000 
php_value post_max_size 50000000

Please note that a server re­start may be REQUIRED for the above changes to take EFFECT.

• Moodle has a site­wide limit called maxbytes that may be set in Administration > Configuration > Variables.
• A limit may be set by teachers in the Course SETTINGS.
