This is definitely an issue with Wishlist, sorry but you’ll need to raise the issue with them.
Sounds like you might have already done that, but their answer seems pretty lack luster.
You can use the following three filters:
bbp_get_forum_class
bbp_get_topic_class
bbp_get_reply_class
Each of them function exactly like the core WordPress post_class filter: http://codex.wordpress.org/Function_Reference/post_class
Are you comfortable with CSS?
Forums look to be showing fine for me as well: http://screencloud.net/v/hmgO
Please note that these are community forums managed by volunteers. You must be patient, especially on weekends.
What version of WordPress are you using?
Do this:
1. Delete the new Forums page you created
2. Go to Appearance > Menus
3. Create a new Custom Link and enter the URL of the bbPress forums page.
Sounds like your theme has its own bread crumbs function. I would suggest you either disable it via an option in the theme (if it has one), or you edit the theme template files to remove the bread crumbs from the forum page.
Why not simply change the forums slug in Settings > Forums?
Can you elaborate a little more? Are you wanting to require members purchase a product or subscription to access the forums?
The sidebar is controlled by your theme, not bbPress. I’d suggest you install the Widget Logic plugin, which will let you control exactly where the widgets show up.
1. Download the latest version from the theme distributor
2. Connect to your site via FTP
3. Upload the theme to wp-content/themes
If you are not familiar with FTP, then you can
1. Go to Themes
2. Click Add New
3. Click Upload
4. Choose the .zip you downloaded and click Upload
You should contact the developer of that plugin as it is most likely a issue (or simply incompatibility) with that plugin.
Are you not running the latest version of your theme?
That’s caused by a conflict with your theme, most likely because the theme is doing bad things to the WordPress queries (to pull in the topics / replies).
What theme is it?
Unless you do some advanced custom rewrite rules, this is not possible. It is also not a very good idea because if you ever need to move a topic to a different forum, any existing URLs pointing to the topic will break.
It should be possible with some custom code tweaks. Are you comfortable with a little PHP?
@Tapirk You need to create a new custom plugin and then paste the function into it. The easiest way to create a new custom plugin is to use Pluginception.
Did you setup the home page of the forums using the short codes? If so, switch to the HTML view of your page editor and you will be able to see the PRE tags.
The usermeta table is one of the core WordPress tables, so usually it will be the one that looks like this: wp_usermeta. Sometimes, however, the “wp_” prefix will be different.
Oh dang, I could have sworn there was one.
Ok now I see the issue with the profile page. If you create a new (regular) page and place the profile short code on it, does it work?
Well check that out, I didn’t know that 
I don’t believe that is a language file included with bbPress, so, no, you will have to update it each time. Though it would be best if you submitted it to http://trac.bbpress.org so that it can get added to the core plugin.
As far as I can tell it appears to be working correctly. Can you give a more thorough example of what it should look like?
