Use phpinfo() to check these settings:

file_uploads should be 'on'

upload_max_filesize should be bigger than the file you want to upload

upload_tmp_dir if empty, it will upload your file to a default path

post_max_size should be bigger than the file you want to upload

and check if you have permission to write to your upload folder.
