There is another thread that addresses this issue but I cannot figure out the end result. The debug log about 100 entries in it in the last few days. I opened the admin panel this morning and went to modules/shipping/table rate and then clicked edit. These are the three debug logs that I got:

The only other thing I remember doing was at the top of the screen in the admin panel there was a yellow highlighted text that said the files were over so many days old so to back them up. I clicked the text and it took me to the admin activity log manager to review or export logs and I did that. Don't know if that had anything to do with it.
