proxy error???

[aton]

logging in, posting comments and everything works.

but when logged in as admin and trying to edit a picture with picEditor, i see the picture, then i choose rotate 90° and 100% quality, click on "save" and get :

Proxy Error
The proxy server received an invalid response from an upstream server.

The proxy server could not handle the request POST /gallery/picEditor.php.

Reason: Document contains no data

Apache Server Port 80

How large is the picture you're trying to edit?  It could be that your server is having problems handling the rotate/resize because of the file size.

Ccan you dupliate this error on a different machine?
