Coding Notes WordPress

ERR_EMPTY_RESPONSE in WordPress and Visual Composer

The Problem

While trying to troubleshoot a client’s website I kept seeing this message when trying to access the Page Menu / Edit a page.

This page isn't working

____ didn't send any data.


Turns out the issue was triggered by the Visual Composer plugin.

The Fix

In apache/.htaccess I increased the SubstituteMaxLineLength level to 10M, the default setting is 1M.

<IfModule mod_substitute.c> 
SubstituteMaxLineLength 10M 

The website was hosted on GoDaddy.
