Clips do not attract and align

Hi. 

For some reason clips on my timeline stopped to align iteslf when I move them around. 

When I moved a clip, there used to be a line which helped position the clip in relation to other clips at the bottom or bottom. now this option is not available. how can I restore it?

Enable snapping button (Shortcut: s, it's easy to hit that shortcut by mistake):
