500 Internal Server error

Is there possibly a path I need to adjust in the index.php of the forums folder?

Hello-
Anyone else run across this issue I am working on? I am thinking that there needs to be a defined path but not sure where?

Well I changed it (under admincp, in server settings, from Mod rewrite to ADvanced URLs) and now they show up.
I am glad that I have the chance to report this back to the helpful group for future users. But, Will this impact seo?
Is this a bug?
Should I persue this as an issue or is it by design?
Thanks.
