I can reliably get the errors to occur so I don't need the conditional.

There is no loop, I just misread some class names that are similar. Still don't know what's causing it. At some point either XenForo's DB connection gets closed or the reference to it is severed.

You do need the conditional. If you don't have one it will throw an exception even if the DB connection is working. You only want one when it's not working. Even if you get the setFetchMode error all the time, the function might only be failing one time out of a hundred calls during the same page load. It's the failed call that we're trying to debug.

Are you unable to fill out the Install Service in the Members area? If you submitted that, I could do all this relatively quickly (we will probably need dumps from many functions within the backtrace) and have a fix for you in a few hours.

I can't give you access to the live production site anymore. But I've got a backup site. I'll verify that the bug presents there and give you access. 3 moments.

Done. The dev site details have been provided. A fresh install of the latest build showed the same error immediately.

I can now reliably reproduce this on your site but only if my XenForo account is not logged in. It seems like it only happens for guests or if a cookie is expired.

I can now reproduce this reliably on my site.

The user must not be logged in, or their session must be expired, AND
The board must be turned off to guest viewing "Options: Board Active", AND
The user must attempt to view any of the wiki_* PHP scripts except wiki_index.php, which will correctly show a login error.

Fixed in the next release. The user should now see the login error.

Hmm, I was doing this when logged in, but I can't reproduce it today on the test site.

Does that mean that Beta3 is ungated?
