Hi Support,

I seem to be having a strange security problem.
I have a forum (which has been transferred to S1) which I imbed in my website
using the following code:

<iframe src="http://southern-men-s-shed-network.131.s1.nabble.com/" width="100%", height="600"></iframe>

If I click on the login option, it displays the nabble login screen.
If I enter my correct details, the screen disappears and returns to my web page but still showing as
Not Logged In.
If I right-click the forum link (top left corner) and select to open in a new window and then use the login from the new window, the login screen appears and login is successful.

I've tried this with different browsers (Windows: IE11, Chrome, Edge and Chrome on Android) all with the same effect.

Any ideas how to correct the login mechanism from an iframe imbedded forum?
