I've been able to replicate this locally ('pure' digit-only IDs don't work) so we'll fix it as soon as we can.
Not spotted our side because we use an asset-numbering system that ensures there's always a mix of alphanumeric characters.
This error appears when I insert Wiris type questions, it is, when I press check button. There isn't any problem with other questions.
Are you able to generate the same error with the language set to English?
Also, if you can turn on Debugging that would give more technical information about the error.
Question ids mismatch
We has some situations like this, and it turned out to be caused by this sort of scenario:
- Create a category and a question with idnumbers embeddable/testq
- Embed these somewhere.
- Try it to see how it looks.
- Change your mind about what sort of question you want.
- Removed idnumber testq from the first question, and then create a new question and give it id testq.
- Now go back and look at where the question is embedded.
Then you see this error.
There was then the problem that there was no way to escape from this situation.
We have done a fix where in this situation, you should now get a 'continue' button which clears the current attempt and lets you start a new one. That code is currently on github, but has not been released to the plugins DB yet.
I have followed all the steps and installed the github plugin, and once more it is written error. It only happens with Wiris questions, with the rest is ok but with this type of questions the screen goes back again to the error screen . I add the screen shot. Thanks in advance.
