I have now 3.8.0 but when I try to upgrade it to 3.8.1, I click Upgrade
then it says:

Your vBulletin version does not appear to match with the version for which this script was created (version 3.0.7).

Please ensure that you are attempting to run the correct script.

If you are sure this is the script you would like to run, click here.

I click Click Here,
then I get this:

Database error in vBulletin 3.8.0:
