It looks like you didn't upload the files correctly or completely. All those mismatches in the file check point to an incomplete refresh of the files on upgrade.
I'd try re-uploading the XF package again and be sure that it overwrites the old files that are there.
You shouldn't need to re-run the upgrade, just replace the files from the original XF package you used to upgrade with.
To be sure, get a fresh copy from the customer area.
