Is this on a production site or a site that is currently in development?
It’s on a site that is already live. You can check it out here. http://bgbureau.com/mainforums/
Weird, everything seems to come up for me.
The Forum shows up, but when I click on the Hello World forum, I get an error on the next page and can’t post any topics or anything of the sort. There’s no “Post Topic” buttons.
What version of WordPress are you using? I suspect something in your theme is attempting to access a $post variable that’s been unset as part of bbPress attempting to work its magic.
You can tell that it’s using the page template, since you have some hard-coded author information in there. It’s probably something in your theme that’s trying to access something that no longer exists.
I’m using the latest version of WP now. It was giving me the same error befoe and after I updated WP.
Still not working. Anything I can do?
If you switch your theme to TwentyEleven does it still happen?
It works fine in TwentyEleven.
If it works with TwentyEleven then unfortunately it’s an issue with you theme (typically the theme is doing something strange and not orthodox).
I’m not familiar with the Arras theme, I would contact the theme author and see if they have any insight.
Without having the theme it’s hard to tell, it could literally be 100s of things.
I noticed the theme is no longer available in the WordPress.org theme repository, looks like it got pulled. That’s a little concerning as themes are pulled from the repo when they are either not written correctly or doing something shady (putting links in your footer, etc).
