Hi there,

We’ve been seeing this error message consistently: “400 bad request – request header or cookie too large – nginx”. This will usually cause us to need to clear cookies to fix.

Last week I had to clear cookies probably like 25 times because it was happening constantly in Chrome. I figured it was because I was making changes to the site and I was logged in. Then today it happened to my coworker and he was NOT logged into wordpress so that got me kind of panicking that it was happening randomly to people trying to access our website.

I asked WPengine (our host) about this and they said that they need to know the cookie that regulates the header because they may need to add an exclusion for it. They told me to ask you (the theme authors) about this. This is exactly what they told me to do: “Ask if there is a cookie that is needed to allow the header to operate and if so, can you provide that to us. Then we can add that in our server. If they respond with no, then you would want to define the header in the config.”

Can you help me with this request?

Thank you so much!

Hello.

Thanks for your reply. I do clear cookies and restart my browser often, so that’s not really a problem. I’m more concerned with other people out there (my coworkers, potential customers, etc) trying to access the site and not being able to due to the error specified above. I can’t tell my customers to clear cookies every week so that’s not really an option.

According to our host WPEngine, one of two things need to occur to resolve this ongoing issue: 1) we provide the cookie that regulates the header to WPEngine. Then they can add that in their server. 2) If there is no cookie, then we would want to define the header in the config (by the way, I have no idea what this means).

Please advise.

Thank you.

Hi there,

This seems to be your server configuration related issue. Please refer to the following resource (https://www.narga.net/how-to-solve-common-nginx-problems/) and forward it to your hosting provider.

Let us know how it goes.
Thanks!
