first of all i have these settings in my htaccess
php_value memory_limit 4000M
php_value post_max_size 3000M
php_value upload_max_filesize 2500M
php_value max_execution_time 300
And also checked the phpinfo page , which shows the same data as of my htaccess file.
But still "Request Entity Too Large" 413 Error shows while uploading a 2gb zip file through an upload script.Why?
