Remository

If you get an error message about "file unspecified" when you attempt an upload, this means that the basic file upload mechanism in your web server is not working correctly. The most likely cause is that the file was larger than the maximum size configured in PHP. You may be able to change your PHP configuration, or you may need to consult your host.

To get more information, download and install the "Remocheck" component. It is purely a diagnostic tool. Follow the instructions given in the repository, and do a trial upload with Remocheck. It will give you diagnostics and information about your hosting. Please also see the FAQ "Uploads and php.ini".
