It appears I defined that column as unsigned, which is stupid.

Doh!

Filed as MDL-27929.

Good Tim.

In timhunt-Moodle-Question-Engine-2-43277d3 it works, but then then you have made some change and it began to give this error.

I don't seem to have a 43277d3 revision anywhere. Weird. Can you describe the version it works in in some other way? Thanks.

Hi Tim,

is it possible to give this issue hight priority. How can I write in my thesis that it is the best LCMS quiz  if it it doesn't work?

Is there some something I can do?

This is on my list for today, I hope.

If you want a quick fix, you can directly edit the table definition (using PHPMyAdmin or similar) to change the question_attempts.minfraction column to remove 'unsigned' from the data type.

Using a BETA version rather than a STABLE one clearly expose to more bugs wink .

If you need a stable version for your thesis, you better have to  use 2.0 stable or wait for 2.1 release at the end of the month.

No. 2.1 is in a state where it is fine to use for research, and helping to find the bugs is a very useful contribution.

Bug hunting is also fun in my personal opinion big grin

I played with 2.1 only for a few days but I too find it very stable. I am now quite sure I will upgrade my production website before the begining of the next academic year.

I notice another problem:

when I go to Courses ->"CourseName" -> Participiants

it go back to Home-> Participants

and not to

Home->Courses->"CourseName"-> Participiants

as I would expect
