Interesting. This thread made me notice that one of my courses, http://www.memrise.com/course/750078/tropical-coral-reef-fish-identification/, shows more learners on its card on the list of courses, than there are in its all time leaderboard. Is there any way that could happen if it weren’t a bug?

I have at least one like that. I had put it down to people adding the course to their dashboard and then deciding to delete it without starting the course. 
[Edit - but looking at it again, there is a big difference between the numbers: 342 on the card in the course list and 154 on the all time leaderboard 
]
If it’s not that, I can’t think it’s anything other than a bug.

Yes, I drew this to @Lien’s attention in my post 4 above this one. I think there may be more than one bug affecting these numbers.
As I understand release was deployed 4 days ago.
Checked the numbers this morning for the two courses that I have been keeping an eye on. One had increased by two since yesterday and the other had dropped by one.

Thanks for the updates! My colleagues will look into it again this week. Apologies for the annoyance in the meantime.

So does anyone know if it can ever make sense for the count of learners on the course card (in the list of courses) to be significantly higher than the number of people on the lifetime scoreboard in the course? I understand the number of learners can be lower if people quit the course, since they’re still on the leaderboard. But since the leaderboard shows everyone who ever joined the course, even with a score of 0, as far as I can tell, then how can the count of learners ever be higher?
This is just a wild guess, but what happens with people who deleted their account while taking the course? Their username would become “deleted”, so they wouldn’t appear in the leaderboard, would they? Could it be that they are still counted as learners for the course because they actually never took the time to quit it? I don’t know how the counter is incremented and decremented, but this is the only option that I see that wouldn’t involve a broken counter.
Another option would be that “quitting” a course doesn’t really decrease the total number of learners but that joining it again still increases the number of learners, so this is a “broken counter” option. I guess some people already checked that the counter was working properly, so this idea doesn’t seem that realistic.
That release updated the count, at least for my course, but it didn’t solve the problem, because it froze again after the update.
Before the update, my course had been at 3.56k for a couple of weeks, the day of the update, it suddenly went up to 3.91k, and it’s stuck at 3.91k again.
Please solve the issue. Thanks.
As far as I can see, all Tagalog courses have been shown as having no change in the number of users for the past several weeks. Improbable, Watson.
any update on this? my number haven’t been changed for a very long time…
I’d like to know too if Memrise staff has looked into this problem. It’s been here for over two months and we haven’t been given a solution yet. I want to know how many learners my course has. I think we’ve waited too long already, it’s time for a fix.

This issue has been the subject of more recent discussion under a different topic: Number of learners stuck
Is it worth merging the threads to concentrate the discussion?
Yes, probably, but I got into trouble doing that once before. It was argued then that there were subtle differences between the subjects of the two threads. The same could be argued here. This one began with a question about the difference between the number of learners shown on the course leaderboard and those shown on the course index. The other thread leads on the topic of learner numbers on the course index not updating.
There is now some cross-over between the two threads but, I am reluctant to get my fingers burned again. That’s why I just added my earlier note.

Obviously Memrise has no interest in correcting this problem. What is it now, four months or five? Or six? No change whatsoever and no feedback. Is anyone at Memrise bothering to read this thread?
Hi @Joshua,
I know there are more important issues running right now but, when you have time, could you take a look at the course learners counter which seems to be doing strange things today.
As you know from this topic and earlier posts in Number of learners stuck, I monitor the number of learners taking the courses I created or contribute to. Even allowing for ‘catching up’ following no movement in the counters over the previous 4 or 5 days, some of the numbers showing today have increased significantly even though the course leaderboards don’t bear this out.
One course, for example, increased from 1654 (which had been the figure for several weeks) to 2182, even though the weekly course leaderboard is showing 42 (ie no spike). Another one, increased from 91 (also the figure for many weeks) to 100, even though the leaderboard only shows 2 people have worked on the course so far this week. There are similar changes in a couple of other courses, and one that increased from 8538 to 8578 overnight.
Is this the result of some wider-ranging catching-up work or just a bug?

Hi, we rolled out a fix yesterday for the incorrect number of learners in a course.
Previously, the task to update the number of learners was not functioning correctly. The correct value should now be displayed, you may notice a huge jump due to this not being updated for several weeks or months.
If your number of learners hasn’t increased, please use the solution provided by Hydroptere, which will manually update the number of learners in your course.
