Faulty PHP deleted my site?

#1

I installed a third party amazon wishlist widget to my blog, and it seems to have deleted everything?

That’s the widget.
I can’t seem to get in through FTP, and every time I try to access any parts of my website to remove it, I get the following message:

“SIMPLE_HTML_DOM NOT FOUND, CHECK IT IS IN -> DIR”

:confused:

Ideas?

Ignore anything you saw earlier, I need more coffee today…

Your site loads and everything there is fine. I deactivated the plugin for you, but that FTP error is truly weird. What FTP app is this?
