Problem uploading avatars and attachments

[Toky0]

I get this message anytime me or one of my users try to upload an avatar.

There has been an error in the upload. Please ensure that the file has been correctly selected and that the upload has taken place successfully.

And when I try to upload an attachment.. Nothing happens. =/

Run the Upload Diagnostics and report back the results:

Admin CP -> Import & Maintenance -> Diagnostics -> Upload

Also, in the Admin CP, open the Server Settings and Optimization Options section and turn on the Public phpinfo() Display Enabled setting. Then provide the URL to your forums. This may help us troubleshoot this problem.

I did everything you said. The results of the diagnostic report are in the attached image. And the link to my forum is http://www.battle-grounds.com/forum

This error occurs when the tmp space on the server is full. You or your host will need to edit php.ini to specify an upload_tmp_dir directory that is on a partition with sufficient space to allow uploads.
