So, no matter what type of file (have tried PDF, PPT, Word, Excel, JPEG, GIF, PNG, etc) I try to upload into the Course Summary Files section (have tried drag and drop as well as uploading it manually) I receive the same error message:
"The file 'XXXXXXXX.xlsx' is either empty or a folder. To upload folders zip them first."
Any assistance would be greatly appreciated.
Also, just attempted uploading the exact same file below, and it accepted it. So...
