[BA-1020] Ghost Words in Community and Official Courses

Description: Previously deleted words in official and community-created courses cause learning sessions to fail launching: “Whoops. Could not load the session”.

Status: Unresolved

Internal code: BA-1020

Solutions/Workarounds: Please try skipping the faulty level. If it occurs on an otherwise completed course and you’re still prompted to learn new words, causing the error, please click on the button with the dots to select a different mode from the ones available.


This lesson → Level 3 - L,M,N,O,P verbs - 114 Verbos regulares frecuentes - Memrise can’t be finished, and I don’t know what. All words are learned but the lesson is marked as incomplete.


The Kanji at chapter 12 dosen’t work after I have done almost everything of the kanjis. I get the message “Woops could not load the session. Sorry” Irritating. I see that the same problem is accuring for others - when will you fix this bug?

Hi @Monisolen, can you please link the course?

@MemriseSupport Could be this one: Level 12 - Week 1 Day 6 Kanji - Nihongo So-Matome N3 Vocabulary - Memrise

This is also a kanji (and vocab) course that is broken on chapter 12.

Hi @LaravZ, this should now be fixed. Please let us know if you face more issues :slight_smile:


It is fixed, many thanks!


Je suis entrain d’apprendre le russe et j’ai ce bug qui s’affiche.

Serait il possible de m’aider? merci d’avance.

Hi there, I hope you don’t mind me replying in English.

Unfortunately due to some inconsistencies in the number of items, Learn New Words is causing an error on this level (Décodage).

In the meanwhile we advise moving on to the following levels and skipping Learn New Words mode (you can skip any session by tapping the button with three dots and selecting a different mode from the ones available).

Thanks for your patience.



thank you, it’s ok for me

In the course Начальный курс корейского языка - by Vandevorst - Memrise are not existing words in 12 and 23 levels, which leed to error.
TTMIK Korean Slang Expressions - by nae_nae_ - Memrise - the same in 26-29, 31, 32, 34, 35, 37-50, 52, 53, 55-59 levels.

Hi @harigamypeople16,

This should be fixed now. Can you try again?
