I am doing the above and uploading a CSV however when doing so it brings no errors nothing anyone know why this is happening or how to fix this??

Edit:

Just found this in the debugbar: error Could not open for reading! File does not exist. For some reason my errors aren't popping up weird , anyone know why it cant read it?
