DRC no connection

I did a DRC but now I got “no connections” to my components and all my bullet points are also weird. Is there anything I can do? Or do I really need to rout everything new.

For some reason it’s full of non-junctions, marked by small green rectangles at the ends of wires which aren’t connected. This may be caused by using too fine grid. In KiCad the junction connection is made with exact coordinates.

Check your grid, make it 50 mils (and never less). Select all and use the context menu → Align Items to Grid, maybe it helps.

Actually align them to grid helped.

I am always using 50mils.

Mind your acronyms.

ERC is for schematic
DRC is for layout

I do not know how this happened, but I see a lot of small green squares:

KiCad always places these squares on open wire ends, and they are always cause for some concern when you see them on a schematic. Recently an ERC check for this has been added to kicad-nightly:
