Well, I called my hosting company and as I expected they told me that nothing has been changed on my server. The database drivers appear to be working fine, I have no trouble connecting to the databse.
I loaded up fiddler to take a closer look and I can see what I assume is the problem. The forum is attempting to set the cookie "WWF" on every response but for some reason the browser is not accepting it.
Set-Cookie: WWF=LV=2006%2D11%2D12+11%3A20%3A59&SID=ebbze5daz73ccf8bdca4za5ff1c9dzz4; expires=Mon, 12-Nov-2007 18:20:58 GMT; path=/forum
When I come to this forum the WWF cookie is included in the request and everything works just fine. When I'm at my forum the cookie is not stored or sent back to the server. I do remember sometime last week the clock on the forum was wrong and I had to set it back. I don't know if thats related or not.
