title: ERR_RESPONSE_HEADERS_TOO_BIG Wordpress/Chrome
body: <p>I'm running into this problem where Chrome is responding with the <strong>ERR_RESPONSE_HEADERS_TOO_BIG</strong> when I try to visit my WordPress instance. I use htop to monitor the server and I see sharp spikes in MySQL and Apache memory consumption as well once the request is made. Finally, if I try to access the site using incognito mode, the site response normally and the error disappear. I looked around and found other related and suggested solutions like <strong>LimitRequestFieldSize 4094</strong> and <strong>LimitRequestLine 4094</strong> to restrict the header size, but with no luck. My environment is as follows:</p>
  
  <p>WordPress version 4.8</p>
