Hello,
My apologies for the delay in response because of country block and protection you have used. i could not log in to your site but now i make it work by using
#teamviwer.
For the remaining 3 strings, (
home, curriculum, events ), You also need to translate the strings from the
vibe course module plugin, vibe custom type and the theme itself.
**The strings like
notification, friends, message, activity etc comes from the
buddypress plugin itself. Refer video tutorial:
https://wplms.io/support/knowledge-base/translating-buddypress-strings-activity-notification-messages-friends/
So please try translating the buddypress plugin for this and also try sync the files before translating.
Then clear the cache and then check.
Please let me know if there is any other string left.
Best regards.
