In my local MAMP site I'm not able to upload any files.

Gives me this error in Chrome:

http://nobel.craft.dev:8888/index.php?p=admin/actions/assets/uploadFile net::ERR_EMPTY_RESPONSE

This error in Safari

"Failed to load a resource: The network connection was lost."

Things I did

  • I've checked the asset folder path
  • makes sure folder is writable
  • nothing strange in the craft.log
  • delete cache in admin
  • download new version of craft and replaced the app folder
  • Have you tried another browser (I'm assuming you're using chrome and the first page of google results for ERR_EMPTY_RESPONSE are all chrome issues)? Dec 17, 2014 at 14:14
  • Yes. Tried Safari. [Error] "Failed to load a resource: The network connection was lost." (index.php, line 0) Dec 17, 2014 at 14:56

That usually means "something fatal happened" when trying to upload the file. The usual culprits are the php.ini max_execution_time and memory_limit settings, but if it's happening for small files too, something else could be going on.

Have also seen it happen when you're uploading an image in a format your underlying image processing library doesn't support. i.e. your server has GD installed, but you're trying to upload a 32-bit PNG. Or you're running an older version of GD or Imagick that has a bug you're hitting.

Check if you have a craft/storage/runtime/logs/phperrors.log file. Any PHP fatal errors will be logged there. If not, then check the Apache error logs to see if it's an Apache problem.
