I also use the Sumac version. Here’s what I did to get translations working:
-
You need to enable
darkLang.
-
Add the Language Selector in Site Configuration.
-
If you are using your own fork, you need to specify it with the command:
tutor config save --set ATLAS_REPOSITORY="your_username/openedx-translations" --set ATLAS_REVISION="branch"
- Then rebuild the images:
tutor images build openedx
tutor images build mfe --no-cache
tutor local start -d
translations don’t apply to MFE without --no-cache — I’m not sure why, but you can ask about this on the forum
After all these steps, translations will apply 100% of the time.
If this doesn’t help, it’s likely that there is an issue in your Open edX installation, and deeper investigation is needed.
Hope this helps!
