Backplate not showing through window glass

I have this problem and im frustrated on why the backplate is not showing through the glass

Please help

It’s definitely the glass?!
When you render without glass you can see the backplate?!
And backplate do you mean the camera backplate or is that a sky or worldtexture/hdri?
Here how to create a composite with backplates

Hi walt thank you for taking from your time to reply.

Yes whenever i hide the window i can see the tone mapped image in the back, im using it as a backplate only but the main light source is the sky texture as per screenshot below.

i tried everything and i cant make it to not display this white plane

Try disconnecting the Light Path node in the World Nodes…
