Problem with Wrapper module

[dbs]

Test it with https://wikipedia.org (not with google.com)

It is a registration form for a newsletter. I have the newsletter system on a different domain name because that system only works with php 5.6

If I understand correctly, this does not work because one site starts with http and the other site with https

Is it right you try to show a signup_form?
The address of the signup-form starts with http: but wrapper allows only https.

Hello dbs,

I have sent you an email with the address.

Hello, you have a link to the problem page for us?
Your external address is https?

I tested the Wrapper module in Firefox.
Security level is standard with firefox.

I have just tested the Wrapper module in internet explorer.
When I open the relevant page, it is also blank at the place where the wrapper should appear.
In internet explorer appears at the bottom of the page.
Only safe content is displayed. In addition, it also displays View All Content. If I click Show all content, the content of the Wrapper will appear.

In admin I created a new page with the Wrapper type.
In this page I pasted the external link in the Wrapper module.
If I then go to the website and open this new page, a blank section appears at the location of the Wrapper.
