captcha error: "Please open a web page in order to use this interface"

I get this pop-up notice whenever I try to insert captcha via the "Webassist/Forms/Insert Captcha" menu item - - no matter what page I open. (See the first attachment) When I use DMX Zone Extension Manager to uninstall Databridge, the webassist menu item does not go away (see the second attachment).

I'm using Dreamweaver CC 2020 [lifetime license] on a Mac running macOS v10.15.7

Do you have a .php page opened that is saved to a defined Dreamweaver site? And do you have your cursor on the page where you want the captcha to be inserted?

Thanks for your quick response, Ray.

I tried everything but nothing worked until I uninstalled the DMX zone Ext. Mngr. and installed and used Anastasiy's Extension Manager. I deleted the Databridge v2.35 extension and re-installed it. That worked and now I'm able to use the captcha GUI. However, I notice that I can type anything into the Captcha security field and the form will not be submitted but no warning is displayed. How do I make certain that the code displayed and what is typed in match and warn the user if it doesn't? If left blank, verification does present an error notice and prevents submission.

Please attach the page so I can see what you have. The answer is to add Server Validation and "like entry" validation. The correct captcha answer is saved in the session and you can compare that to the user posted field value.

Thanks, Ray. I'll try your suggestion but meanwhile...

I'm attaching the page. As is, the form does submit and verification prevents submission but there is no warning that the security code displayed and what is typed in do not match. Please review and let me know what I've missed?

This page has the email but I don't see the form. Anyway... you would want to add server validation for "Like entry" with the form element from the form page compared to the captcha session value.

I added the "Like Entry" validation and will test further. I am including the updated form (which is presented via an iframe and thus is a separate page)... attached below for your review. Let me know if it looks OK to you?

The trigger for the form validation should be the same as the trigger for the email or else it could be bypassed.

You are using Required Entry validation instead of Like Entry validation... That would only ensure they enter a value, not the correct one.

Fixing those two issues you should get something like:

<?php require_once("webassist/form_validations/wavt_scripts_php.php"); ?>

<?php require_once("webassist/form_validations/wavt_validatedform_php.php"); ?>

<?php require_once("../webassist/email/WA_Email.php"); ?>

<?php 

if (isset($_POST["addcontent"]) || isset($_POST["addcontent_x"]))  {

  $WAFV_Redirect = "";

  $_SESSION['WAVT_inclcontactinfo_510_Errors'] = "";

  if ($WAFV_Redirect == "")  {

    $WAFV_Redirect = $_SERVER["PHP_SELF"];

  }

  $WAFV_Errors = "";

  $WAFV_Errors .= WAValidateLE(strtolower(((isset($_POST["Security_Code"]))?$_POST["Security_Code"]:"")) . "",strtolower($_SESSION["captcha_Security_Code_1"]) . "",true,1);



  if ($WAFV_Errors != "")  {

    PostResult($WAFV_Redirect,$WAFV_Errors,"inclcontactinfo_510");

  }

}

?>

<?php

if (isset($_POST["addcontent"]) || isset($_POST["addcontent_x"]))     {  //WA Universal Email

  $Email = new WA_Email("incl_contactinfo");

  $Email->From = "".((isset($_POST["Email"]))?$_POST["Email"]:"")  ."";

  $Email->addTo("randyrie@rjrwebz.com");

  $Email->BodyFile = "../email_block.php";

  if (function_exists("rel2abs") && $Email->Redirect) $Email->Redirect = $Email->Redirect?rel2abs($Email->Redirect,dirname(__FILE__)):"";

  for ($emailGroup=0; $emailGroup<sizeof($Email->To); $emailGroup++) {

    $Email->Subject = "Contact Form from RjRwebs";

    $Email->send($emailGroup);

  }

  $Email->close();

}

?>
