New Install, Error 500
Installation and Configuration
Welcome to the Jamroom forum!
You want to check your web server error log - when you get a 500 error, that's an error at the web server level - that happens before Jamroom is even loaded, so Jamroom cannot write to the error_log. You should have access to your web server error logs in cpanel. The usual culprit is that mod_rewrite is not enabled on the server, or another apache module that is part of the base install hasn't been activated.
So you'll for sure want to address that before JR is going to function right.
Let me know if that helps.
Thanks!
