"[Solved] Cannot Upload Object: 500 Internal Server Error"

I have RapidAnalytics installed on a remote server. I'm connected to the remote RapidAnalytics repository via RapidMiner on my local machine.  I'm using HTTP to communicate between client and server.

I have an 3MB excel file that I am trying to import into the RapidAnalytics server.  When I import to a repository on my local drive, the import goes just fine.  When I try to import directly into the RapidAnalytics server, I get the following error:

Cannot Upload Object: 500 Internal Server Error

I get the same error when I try to move the imported file from my local repository to the remote repository.

Any idea why I'm getting this error?
