Re: Error upgrading to 2.6

I tried using the godaddy server by creating a new database by importing my current 2.2.6 data then copied over the 2.6 files and updated the config file.  Once again everything went as planned until I got this message AGAIN;


Error writing to database

More information about this error

It is usually not possible to recover from errors triggered during installation, you may need to create a new database or use a different database prefix if you want to retry the installation.

Debug info: Duplicate entry 'grading' for key 'mdl_quizrepo_nam_uix'
INSERT INTO mdl_quiz_reports (name,displayorder,capability) VALUES(?,?,?)
[array (
0 => 'grading',

2 => 'mod/quiz:grade',

What on earth is causing this?  Why would the quiz table be causing such an issue?  I have marginal database skills but it seems like the 2.6 files are trying to overwrite the old quiz table but the old table is not allowing the overwrite.  Can anyone provide some insight into this problem?
