[Plugin: Timthumb Vulnerability Scanner] Site down: A TimThumb error has occured

I installed the Scanner, ran it and it found two possibly vulnerable files – thumbs.php and connections.php if I remember correctly. I let it replace them, but now my site is down and all I’m getting is this:

A TimThumb error has occured

The following error(s) occured:
No image specified

Query String :
TimThumb version : 2.8.10

Please help!
