Quiz Equations do not display properly when inserted.

[jaesunglee93]

When I type an equation in the equation editor, the equations look good. However when I press the insert equation button on the quiz, It comes out as for example:
 \(E_i\:=\frac{\:\left(row\:total\right)\cdot\left(column\:total\right)}{total\:sample\:size}\)

I tried deleting browser history, cookies, and data on chrome and firefox to no avail. How do I fix this?

Thanks.

me too. what gives?

This literally started happening to us yesterday and we have an exam tomorrow 😑

We also saw this, Wednesday Nov 18th, arounf 5pm-9pm EST.    Equations that had been previously entered and working were showing their underlying LaTeX code, and when student would take the quiz, the equations would display momentarily then display the word null.    

The issue seems to have fixed itself around 9pm, but this would be catastrophic to happen during an exam.    Hoping someone else has some insight as to what happened and will it happen again.

We also have this issue and it affects all of the quizzes in our class (all on the classic engine). It looks like it is trying to default to the new quiz engine with the latex escape characters '\(' '\)'.

We are also seeing this and have an influx of questions from our users. Was this designed behavior?

Happened to me also.  Thought it was something I did, like change a setting but I can't find any settings that would effect this.  When I edit my previous quizzes the same thing is happening when before all looked good.

I will say that when I preview the quiz, the equations are display correctly.  It's just when editing I only see LaTeX code.

We have opened a ticket on the display issue with the Equation Editor. Here is the ticket number: 06970088 and here is a screen cast of the issue:

Exams are coming up.  Please resolve this ASAP.  The old quiz is practically unusable right now.

[pauld2]

I am having the same issue.  Thank you...

[Robbie_Grant]

Product for the win! They have fixed the issue with the Equation Editor!!!

[crafte]

Instructure fixed the equation issue. It is working for us now.

[hlee897]

Still Having issues here.  Some questions show weirdly as shown in the attachment and in some cases, part or all of the questions have disappeared and do not show at all and display [Math Processing Error] in red letters.  The exam is tomorrow.  Please fix this.

We also have a report of the Math Processing Error when trying to insert even the simplest of items from the equation editor. The professor indicates that it also causes her screen to flash when it happens. Does anyone have a ticket open on this, rather than on the original problem with displaying LaTex?  

[dgreen1]

We are having the same issue. Finals are this week for us as we started early.

[ltaylor10]

This is still an issue for us as well.

[ccguy]

Instructure tells me that this has been fixed for new files, but is still affecting ones created between Nov. 17 and 19. That corresponds to what the instructor who raised this with us originally.

I have this problem on just one question on a test. Just in the Preview. Any help from anyone?
