I'll take your word for it. I have managed to find an older version of the program that does not use PDO, just to get me going. I don't like the idea of having a site and not being able to use it.
I will continue to search for a solution to this problem, but until you hear from me again, don't worry on my account. This site is so much faster than my old site and so much easier to use, I am over the moon!
