I had to remove this serialization function as it also
existed on line 64.
This was causing the vhost options to be serialized
twice, Then when the options were being unserialized, the result was
yet another serialized string instead of an array. This is why in the
Web interface document root had a value of "a" no matter what I tried -
because it was taking the first character of the serialized string.
