Thanks to everyone who took a minute to let me know my site was having issues over the past few weeks. I do appreciate the heads up!
Thankfully I am now upgraded to a much more recent version of SubText (thanks AC) and I have changed hosting providers. After nearly two years dealing with sub-par service at WebHost4Life, I have moved to OrcsWeb, and I have to say their service has been outstanding. I have literally been floored by the fast and friendly responses and the quick way they handle support requests.
So now my contact page is back working, and my page load times are back to normal. Yay!
