Closed Unassigned: Fileupload shows completed then "(error)" [27907]

So I am very very new to programming and asp.net. I did alot of searching and gotten this far and have been stuck for 2 days now.

I am using VS 2013 ultimate. Locally I can run the project and uploads the file. That works fine.
Then I upload the files to the web server and all looks good.
I upload a jpg file and see the progress bar goes to 100% then it would error out. The file was not in the "Folder".

I need help.
