[galaxy-dev] New to supporting Galaxy (local deployment) seeking help related to upload problem and log file locations

I've recently been asked to support a local Galaxy deployment. As I am new to the software, I'm having a hard time tracking down logs and honestly understanding how the system works. The actual problem is the scientist in question is not able to upload files. The only upload feature I noticed running on the server was an sftp-server, so I restarted that, but it doesn't appear to have fixed anything. Which lead me down the path of tracking down log files to help me troubleshoot, but I am unable to track those down. I have looked through several of the previous discussions regarding uploading, and have not been able to find the answer to my question. Any help would be appreciated. thanks Zack
