Thanks for posting a question. I'm more than happy to assist you. I've talked to a higher tier of support about installing PECL uploadprogress and it appears this cannot be installed on a shared hosting account. To install PECL uploadprogress you must be on a VPS or Dedicated hosting package.
If you need further assistance please feel free to contact us.
So.. how does one install PECL uploadprogress on a VPS?
Installing the PECL uploadprogress on a VPS requires that you have root access. It is a command line procedure that would require several steps. We don't advertise those steps since it is very easy for someone to damage their VPS/dedicated server installation if it is incorrectly installed. If you have root access and are aware of the risk, then you are welcome to try it yourself. You can find the instructions for installation by going to the documentation provided here. Please make sure that you have a backup in place to prevent any issues.
I hope that helps to answer your question. Please let us know if you have any further questions or comments.
