I'm getting an error that prevents me from uploading logs

… and it won’t let me post what kind of error in the title for whatever reason.

After selecting which fights to include in the upload and clicking ‘Go!’ I am immediately prompted with the following error. It’s the first time I have received this error, and it prevents me from uploading the logs. I have reinstalled the application, which didn’t change anything.

Is there anything that can be done to save the logs?

Fixing now.
