I had already recreated new Security Assist Pages with Data Bridge before reading your response to my post.
I found that the registration page when previewed had error but that was corrected by downloading the Security Assist Files that you made available in response to other forum members with similar issues. I uploaded the WA_RandomPassword.php file and the error was gone.
I now find that the First Name Textfield of the Registration form has a minmum requirement of 6 characters, which was not a feature of the previous Security Assist pages I had earlier removed.
Please have a look at the screen capture and advice on what needs to be done to remove the minimum character requirement from the First Name Textfield.
Ignore earlier post. I have sorted out this particular issue. Thank you!
