Installed the open-source version, get a 500 error on the main page.
I'm not professional IT, but relatively tech savvy, so I was able to get things installed, but can't read the stack trace sufficiently well to identify the problem.
Stack trace is as follows: Error Code: 500 Error Message: Trying to access array offset on value of type null Stack Trace: [click to toggle display]
