Almost all errors with the judge upload occur from deleting or re-arranging columns in the template. You may not edit the template.
Please check the template you uploaded and make sure that:
The file is saved as a .csv file
The headings in your upload file match the order of the template
No template headings are missing
There are no spaces after a judge email address
Check out the template here.
Important note: Tags and Sessions
If your upload contains Tags or Sessions, these must be added to RocketJudge prior to the judge upload.
If you have issues with the Tags or Sessions saving, confirm that your acronyms match what you've previously entered in the Tag and Schedule tabs.
