I have deactivated all my plugins. The only one turned on is bbPress. The page loads half way then gets the error:
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@raptureintheairnow.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Some of the sub forums load with no problem like:

I called my hosting company and they said to disable all plugins and turn them back on one at a time. bbPress is the only one turned on and getting these errors.

I’d deactivate the plugin, then delete it.

Then add as new.

Sounds like it may be corrupted somewhere.

You won’t lose any forum data by doing so

I tried that and still get the same error. I tried changing themes from 2011 to 2013 and the site works. So I am thinking there is some problem with the 2011 theme.

2011 should be fine with bbpress – perhaps it’s 2011 that’s corrupted?
