Request Header Or Cookie Too Large

Going into the category of Web Themes and Templates I got an error from 2 days. Why?
"# 400 Bad Request

Request Header Or Cookie Too Large nginx"

Hi @gabitom,

The Web Themes and Templates page seem to work fine now, but if you are still receiving this error, it could be a cookie issue, please check this solution here: https://support.mozilla.org/en-US/questions/918154#answer-308783 (it also works for Google Chrome or other browsers).

They also advise checking these possible causes: http://en.kioskea.net/faq/15289-google-nginx-404-error and https://support.mozilla.org/questions/811399
