@koldLight doing a google search for “nginx net::ERR\_INCOMPLETE\_CHUNKED\_ENCODING” it sounds like it could be a permissions problem on your server. When nginx proxies a file over a particular size it can write it to disk as a temporary file, if the permissions on it’s directory are incorrect then it can result in the error you’re seeing. There’s a related stack overflow answer here [ruby on rails - net::ERR\_INCOMPLETE\_CHUNKED\_ENCODING nginx - Stack Overflow](https://stackoverflow.com/a/32852154/1163866) If it doesn’t seem to be that, maybe look into the resource usage on your server to make sure you’re not hitting any memory or disk space limits. --- _[View the full topic](https://forum.ghost.org/t/referenceerror-define-is-not-defined-on-admin-page/11214)._
