There are some times when the libraries can run out of memory if a
raster is very large, so you can have something that something like a
graphics editor e.g Gimp can open OK but Qgis coujld have trouble
opening it.

I think that there is something wrong with the Tif file I was using.
I had the same problem with a couple of files but I went back to the
source file and redid the referencing and it is ok.

This is a generic answer, as more information would be needed to
determine exactly the situation you are experiencing.
If you zoom to the layer, is it then displayed in the same place
as the rest of your map?
My recollection of the georeferencer is it produces a world file
to go with the layer. This should have the correct top-left
coordinates and pixel resolution in it. Is there also an XML file
that specifies the CRS?
Look at the layer name where it is loaded in the GIS and see if
there is a question mark displayed next to its name, that
indicates QGIS doesn't have enough information to position the
layer, such as the information that is stored in sidecar files.
It is also possible if the file is very large that it will be slow
to display. Also have a look at the error log at the bottom of the
screen to see if any error messages are displayed.

i have been successfully using the georeferencer for some time.
i referenced several maps and they succesfully georeferenced
and displayed for me.
Then, i was digitizing and i ran the georeference tool and for
some reason, the new referenced maps do not display. i have
exited and tried to georef in a new project and made sure that i
have the same CRS for the basemap and the georef tool but when i
run the referencer, the layer appear but the map will not
display. i have tried restarting, clearing the georef tool and
running again but i get the same result. Does anyone know what
i am doing wrong and why my referenced maps will not display?
