How do I fix a lighting / glow leaks?

I’m getting a weird glow between my walls and my floor, I’ve tried rebuilding the lighting and using “End” to snap to the floor but it’s still there,

I’ve also noticed it seems to go away when you are certain distances if you sit still but any movement brings it back.

Ok the problem is solved now

Solution:

He has accidentally connected his texture to the world position offset node.
