mod_fcgid: HTTP request exceeds MaxRequestLen

On a ISPConfig server with PHP running in FCGI Mode, i get following error in error_log when upload images from WordPress admin area.

[Tue Apr 03 13:45:11 2018] [warn] [client 112.133.237.47] mod_fcgid: HTTP request length 139264 (so far) exceeds MaxRequestLen (131072), referer: https://www.url.com/wp-admin/media-new.php

ISPConfig store error log for site in “log” directory in parent folder of document root. In this case, it was

/var/www/clients/client0/web1/log/error.log

To fix the error add

FcgidMaxRequestLen 1073741824

to fcgi.conf

On Ubuntu/Debian, you file location is

vi /etc/apache2/mods-available/fcgid.conf

On CentOS/RHEL

vi /etc/httpd/conf.d/fcgid.conf
