Sorry, no one has access to the openpilot forum, it doesn't exist anymore. The only openpilot server that's still online is the www one and it hasn't been updated in months. The forum and wiki are just gone. Google and Bing search results will continue to show them for another month or so believing that they're just down temporarily and then they'll delete them.
If you really want to see what was said there there's a chance that archive.org has archived the page. Take the url that google says the page was and put it into archive.org. I've had reasonable luck with that, successful perhaps half the time. And google has text only caches of most of the pages that you can click somewhere near the end of the url in the search results and ask for the cached page. It's worth a try anyway.
That said, the people who founded librepilot and hang out here were the top experts at openpilot (in my opinion anyway) and if there's any way to fix your problem they'd be your best bet.
edit: I just ran a search for what you said and neither google nor archive.org have that page cached. Still, in general my advice above gives you a chance to find a copy of the information.
