Server PHP Errors

Why would some people in certain parts of the country be getting a PHP error on a website and other people in different parts of the country not be getting the error?

The error they are receiving would be a good thing to post.

Does the site use any geo based DNS?

Let me know if you get the error: 23.101.151.179 fill out form and submit.  That is where folk get the error.

I did get this error.  It really looks like you need to track down the cause of the "Undefined variable: DB".   Wether it's the direct or indirect cause, that's probably the key.  Not being able to see the actual code, I can only say what I would do.  Have you checked the line number and code around it to see if there was something amiss?
Looks like you have PHP running on a Windows system.  May be a permissions issue?  You can turn on debugging in PHP also, and look at your web logs, these are going to hold the biggest clues.
I'm also hitting through a proxy, so tried hitting it direct.  Got the same error.

OK. This is what I can see and it seems odd, but it might help you to track down what's going on.

Yesterday when I tested this for you, I didn't get the errors. Just tested it again and didn't get any errors initially. Here's the weird part - If I enter an email address of test@test.com, it works fine. Any other email address and it bombs out.

This tells me that somewhere in your code it's doing a database lookup regarding the email address. I'm guessing that test@test.com is probably in your database (it's a common address people use when testing), and so no error is generated. Addresses not in your database are causing problems.

Have a look at your database and try the form using an address that already exists, and then try it with addresses that don't exist.

I know that won't solve your problem, but it may help you focus your attention in the right place.

Of course, I could be way of the mark, and something else is going on :)

That was it.   There was a spelling mistake in on of the if clauses.  Man, I feel dumb right now.
