Hi guys,

I get the above error message at the top of the page whenever the edit profile page is accessed. Otherwise, the page loads and functions normally. Please advise.

Thanks!

Actually, everything is fine when signed on as an admin, where the fields are different. When signed in as a member, the error message appears, and the Manage Avatars and Manage Membership blocks do not appear as expected.

I got rid of the error message by adding the area highlighted in red as suggested by deano, but I'm still missing the avatar and membership admin blocks.

function htmlspecialchars_adv( $string ) {
    return htmlspecialchars((string)$string, ENT_COMPAT, 'UTF-8');
