Upload progress bar error

Per instructions in another topic, I was able to get videos to upload by disabling the progress bar. But I would like, if possible, to fix whatever is causing this error. I am using the host suggested by the script authors, it said they support this script. What can I do to here?

You can contact [email protected] to get that fixed.

Which host are you using?

I figured this out from into in the other post with the same issues. Thanks...
