Unknown column 'a.access' in 'where clause' --- Manage button message quiz

Unfortunately, we can't give any login due to our policy towards our customers. Tell me what i need to look at to resolve this.

Thanks, that's what i needed.

Now i've got an other issue. When i try to check my subscription to the component. It said : "You do not have a subscription. Please click on Redirect to subscribe now."

But in my wdmtech account i've subscribe until january 2018.

Could you help me ?

Thanks for your reply.

We have 2.5.9 vQuiz installed at the moment. How could i download the latest one ?
Updated site are check in joomla but didn't discover any new update.
And from our account here, we can only download a quick-start.zip

Is there a .zip to upgrade the component/modules ?

Hi,

I've got an issue when i try to manage quiz logged as administrator (not super admin).

I can't manage Message Button in the main settings.. The pop up end up with this error "Unknown column 'a.access' in 'where clause' ".

I check the rights in the ACL of quiz, my administrator group got all rights on the component.

So where is the problem ?

Thanks in advance !
