How to Fix “mod_fcgid: HTTP request length 131619 (so far) exceeds MaxRequestLen (131072)” error on Ubuntu 12.04 LTS (Precise Pangolin) Linux.

If you are trying to upload a file through WordPress or another content system to your web site and your website is running on Apache2/PHP5/mod_fcgid, and your browser displays the error:

Browser error
Internal server error

and in your Apaches error log you see something like

Apaches error log
[Wed Nov 07 13:12:45 2012] [warn] [client 192.168.XXX.XXX] mod_fcgid: HTTP request length 131619 (so far) exceeds MaxRequestLen (131072), referer: …

This error is because the default value of FcgidMaxRequestLen is 131072 which is very small see Apache Module mod_fcgid for more information.

First check in your php.ini that upload_max_filesize has a big enough value for your upload. The default in php.ini is upload_max_filesize = 2M which stands for 2 megabytes (MB). If it is not set, set it to

Set php.ini
upload_max_filesize = 2M

Next edit your file /etc/apache2/mods-available/fcgid.conf, or if you have Virtualmin installed go to Webmin> Servers> Apache Webserver> and select the Global configuration tab then click Edit Config Files. Now select /etc/apache2/mods-available/fcgid.conf in the dropdown list then click the Edit Directives in File button. Either way you should see something like this.

Current directives
<IfModule mod_fcgid.c>
AddHandler    fcgid-script .fcgi
FcgidConnectTimeout 20
</IfModule>

You now want to add the FcgidMaxRequestLen 2097152 directive to make the file look like this. NOTE: FcgidMaxRequestLen 2097152 = 2MB.

Edit directive
<IfModule mod_fcgid.c>
AddHandler    fcgid-script .fcgi
FcgidConnectTimeout 20
FcgidMaxRequestLen 2097152
</IfModule>

Now save the changes and restart Apache with

Restart Apache
/etc/init.d/apache2 restart

Or if working in Virtualmin there is a Stop Apache link in the top right hand corner of your screen click it and when Apache has stoped the link will change to a Start Apache link. Click it also. And that is it you will now be able to upload your 2MB files.
