400 Bad Request error viewing Live previews

Hi! Since several weeks I’m experiencing an issue with the whole Envato website…every time I click on “Live preview” button of a Wordpress theme I receive this error: “400 Bad Request Request Header Or Cookie Too Large nginx”. I can load live previews of only few sites. Anyone could help me find a reason for this problem?
Thanks a lot!

Hmm that’s a strange one since Live Previews are hosted by the author. Please open a Help ticket. They will be happy to help.

It’s more likely browser cache issue. Clean the browser cache and try again
