Hi Kieran,
I don't know what caused that last problem, but I spoke directly with the server tech support and he removed some redirect code that I don't know how got in there. I mentioned this problem with calendar and he suggested deleting WP Super Cache and try another. So I loaded W3 Total Cache and right now everything seems to be working swimmingly! Cross my fingers!
Thanks for your help and suggestions.
PS. I love the calendar and its perfect for what we're doing with volunteer sign up.
