How to avoid Request Entity Too Large 413 error

Question

How to avoid this 413 error ?

Request Entity Too Large

The requested resource /serverpath/reports.php does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit.

Apache Server at demo3.website_name Port 80

So, could any one please help to set php.ini and how to set htaccess to allow overwrite status

Answer 1

Try to look for the following line in the php.ini and set it to the size that you require:

post_max_size = 25M

You can then set it in the .htaccess file:

php_value post_max_size 25M

Answer 2

Unbeknownst to me, a backslash was being added to a custom font field in a WP Plugin that I had, and another character was being added every time I navigated away from the page. Eventually I had a massive string of //////////s and this resulted in a "request entity too large' error. MY ISP upped the max post and vars = in my .ini but this did not solve the problem. It was solved immediately upon discovery and removal of the massive text string. Hope this helps someone else.

How to fix it in NGINX? client_max_body_size

To fix this, you need to increase the value of the client_max_body_size directive. This directive defines the maximum amount of data Nginx will accept in an HTTP request. By default this value is set to 1 megabyte, meaning if you attempt to upload a file larger than 1 megabyte you'll be getting an Error 413: Request entity too large page. You can insert this directive at three levels:

• In the http block: this will set the directive value for all server and locations in your configurationn

• In the server block: this will set the directive value for all locations of one particular server

• In the location block: this will set the directive value for one specific location in a particular server

In this example I'm going to insert it in my http block and set it to 500 megabytes:

http {

    client_max_body_size 500M; # allows file uploads up to 500 megabytes
    [...]
}

Answer 4

On Apache 2.4 it is worth looking at the LimitRequestBody directive as well. It can be configured per vhost and it goes into the <Directory> section.

<VirtualHost *:80> 
  [...]
  <Directory "/var/www/public_html"> 
    [...]
    LimitRequestBody 33554432 
  </Directory> 
</VirtualHost> 

The size value is in bytes. This finally solved it for me when I tried both the php.ini max size directives and was still getting errors.

Answer 5

php.ini has a setting called post_max_size, which is set to 8M by default (on Ubuntu at least).

Consider increasing that value if you are posting a lot of data.
