The same happens with the course Stein på stein (2014), level 4 (2.2 Bestefar forteller): https://app.memrise.com/course/783148/stein-pa-stein-2014-2/
It is broken both on the web and in the app.
Hi, I have the same problem in level 4 of my course(oxford word skill (intermediate), Oxford Word Skills Intermediate - by shmuma - Memrise).
I’m using Chrome and the error pops up after pressing the “learn new words” and “continue learning” buttons.
@beastieboy00 @alain_zhang @sheidamjn137454 it looks like the creator of the courses you mentioned also left out a translation or entered a blank item, which can cause an error when trying to Learn New Words. These have now been corrected, so the courses should work as normal.
@Methuen I’ve had another look at this course and can see that the course creator has actually left audio off of many of the items of level 15, which means the tests won’t work 
Unfortunately, they don’t appear to be active on the community so I’m unable to invite them to review this.

Hi, I have the same problem in level 10 of my course Trigedasleng Trigedasleng - by MarvelOClay - Memrise
I’m using Chrome and the error pops up after pressing the “learn new words” button.
Hi all, it seems like you are all experiencing the same problem. When a course creator has accidentally left some columns blank when adding items, the system will return this error.
@18lujaynaha @miinanyaaaaan @mattwyatt123 Please try the courses you mentioned again as it should now be fixed.
@LoraKomSkaikru I’m afraid there’s several missing translations in this course from level 6 onwards, which the creator will need to complete in order for this to function well. It doesn’t look like they are active on the community, so I’d recommend choosing a different course for this language.
If you keep experiencing this problem, we’d recommend first seeing if you can reach out to the course creator in the forum by tagging them and asking them to double check through their course to see if there is any gaps/missing translations

I am also having the same issue. I believe since it says I need one word left and it is a word that is in another level, that it glitches and does not know that I already learned the level, thus marking the level as incomplete, when I learned all the words already.
Same issue in Memrie’s French I course.
Yesterday this happened occasionally. Today it’s consistent.
I have tried. Memrise is the course creator.
It’s more than a little frustrating to have paid for a year and then not be able to complete my first course.
@rosquet42 If you are learning an official Memrise course, you will need to refer to this thread or our FAQ page which explains how to resolve this issue.

Do you mean a teaching column blank (as the system provides lots of columns and only two may be used) OR
do you mean an item (ie line entry) in a pair being tested?
Hi @DW7, sorry for not being clear. The error occurs when either a whole line is left blank, like this:
and/or when one of the items is missing a translation, like this:

Hi @maciaszekw1706, thanks for your report. I’ve moved it to this thread as the issue is the same as above. Unfortunately, the course creator has missed out several English translations in level 26, which they will need to complete in order for this to function well. It doesn’t look like they are active on the community, so I’d recommend ignoring all items in level 26 in order to complete the course.
