Why is my new Shapefile layer not showing up?

if you got error in both OS and you can see the information on attribute table, maybe there is a problem with the Coordinate Reference System (CRS).

• First, when you created the shapefile through "Add Delimited Text Layer" tool, did you assign the CRS?;
• Second, when you create the project, are you sure that all layers are in the same CRS; If do not, did you activated the option "Enable on the fly CRS tranformation" on the Project Properties window?

Right click on the layer, Zoom to layer. Once you are there, are the coordinates realistic?
