shp file review error

out_of_range_error.py

>     I'm getting an error while trying to access the review page after uploading files. I get a list index out of range error. I'm guessing that this is happening because the script can't access any of the items I uploaded to the webpage, maybe the database is empty? How do you think I might be able to solve this? Here's the error:
