Interesting…
The problem went away after I turned on the redirect link again.
I just installed Fast Secure Contact Form and get that error on line 474 also.
I’m using Form 1 on WordPress 3.0.4 with the Thesis Theme (version 1.8). I didn’t make any changes to the default settings at first, but since then I’ve tried changing the redirect link and turning it off altogether. It didn’t seem to help.
