Re: Never Validates, page is ALWAYS invalid

This is quite a common problem with reCAPTCHA V1. Check out this site: http://bit.ly/1LhpYoP Wait forever to get a Validation. It's a total pain.

I started out with an older version and I kept getting the error "value cannot be null parameter name:Challenge".  I looked up this error and lots of people said it would be a visibility issue, but this is on a postback from a button click, so there isn't even a chance to have changed the visibility.  I finally followed another bit of advice from a forum and upgraded my version of the .dll  Now instead of the above error message it just fails the Page.IsValid every single time, no matter what anyone puts in. The code is very simple: If Not Page.IsValid Then             TplCommentError.Text = "Please try again to decipher the scrambled letters"          Exit Sub          End If -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
