Our Context

Recently, while working on client website with “Elementor” drag drop builder, we weren’t able to save a page with large content because of this error. We tried increasing php value for: “upload_max_size”, “post_max_size” and “max_execution_time” without any success. Went through “Elementor” requirement and set up all the settings value greater than what was needed for it but it didn’t work.

Researching more, we figured out one possible solution was to increase “LimitRequestBody” directive value for Apache servers and “client_max_body_size” for NGINX. We tried increasing these values but with no success.

Actually, we were using Plesk server with Apache so, tried researching on Plesk support docs and figured out that the default value for “SecRequestBodyNoFilesLimit” was low. You will have to increase the value for this parameter as required. File to be edited can be found at:

/etc/httpd/conf/modsecurity.d/rules/tortix/modsec/tortix_waf.conf
or
/etc/httpd/conf.d/mod_security.conf

Finally, after increasing this value and restarting Apache server fixed this issue on our end.

We hope this article helped you learn how to fix the WordPress 413 server error when increasing basic php settings doesn’t work.
