Only small image upload

[eK3eKyToPa]

I cant upload images with size over 640x480 only lower. When width is 640 an error message is shown:

The following error was encountered:

    * Zero Sized Reply

Squid did not receive any data for this request.

This massage is shown after choosing an album tu add the picture.
The size set in configuration is 2048. Pretty big. Somewhere else is the problem but where ?

     Thanks

I do not know squid very well, you should ask your host... a common problem together with that error message is php/ apache configuration. Therefore I'd suggest to raise the php mem limit first
