Fatal Error (Read 17 times)

Since last night, I get a Fatal Error when I try to log my miles. I am doing the mileage game, and my deadline was last night. Can we figure out how to add my miles?

Google Chrome

Chromebook

I hit "save" and received this message:

Fatal Error

An unexpected error occurred while processing your request. If this problem persists, please contact me.

Now, I went to my log and see that the workouts are there three times because I tried to log it three times. However, now I cannot delete any of the. I click the X, get the pop-up that makes sure I want to delete it. I choose OK, and nothing happens except the pop-up goes away. I added the rest of my workouts despite the fatal error message, but I have two duplicate workouts that should not be logged for the game, but I cannot delete them either.
