Oh, and if you want to test it without having a lot of test posts show up. Type your test in the Quick Reply box and then rather than clicking "Post Quick Reply" click "Go Advanced". That also triggers the Forbidden message. If you get the advanced page then the text you entered will post.

python_ is a programming language, I think something is catching the keyword and kicking it out.

But then it should do so generically on vBulletin.

I think it goes though Apache first, so I'm guessing it's in Apache.

Yep, that's what I just realized.

Note that putting python_ in any submitted form on LoT gets this result (search page, for example).

This reminds me of BTD's signature

Can't quickly find anything on this specific method of producing the error but searching "apache forbidden python" will get you plenty of examples of it. Looks like it something in the Apache httpd.conf.

Don't know if that means going through the LoT hosting company or if that is something under direct control. (Assuming of course if something so random is worth the fix).

Personally, Lisa and I would probably be fine with anything that makes discussing Monty Not-Funny more difficult.

We aren't the only ones. Here's what I found on the vbulletin site:

Error sending PMs with the word Python_ in them?

Damn. Your Google-fu is more powerful than mine today.

I just can't believe that I didn't immediately notice that it was a server error and not a vBulletin or PHP error.
