signup form error message page is greyed out

Hi,

This is a Buddypress site with extended Profile fiiles. Membership, TOS, Pro SItes plugins are installed. The Scholar theme is being used. All are the latest versions.

When the user submits a signup request with an error, such as an invalid Signup Code the resultin page has the regular headers but the rest of the page is greyed out. Any suggetions as to why this would happen? BTW, if there are no errors, the form works fine.

I turned of TOS and tried the BP default theme, but the problem remains. Also, I'm not sure when this started.
