As mentioned the the documentation, the 500 errors are internal server errors and your server error logs would have details for this. Let us know the error details from log so that we can suggest.

Please make sure that your server meets the requirements mentioned in the docs, specially the mysql mode. Once we have the error details we will be in position to suggest solution.
