Progress bar will not initialize

Every time I try to upload a new video I get an error message that the progress bar did not initialize and the upload fails. Is this a bug with the software or is it a server issue and how do we fix it? Thanks and I hope someone can answer this because we are dead in the water if our users can't upload.

Please disable the upload progress bar and try to upload a video .For this include /settings/upload.php
$use_upload_progress_bar = 1; replace with $use_upload_progress_bar = 0;
