Import error ; collection - This course cannot be used

[danysvnt]

Was trying to import some video in french and almost every time I get this error

[zoran]

What happens if you try to import to any other course?

[danysvnt]

It doesn’t work either, tried with other videos too

[zoran]

Can you try to create a new course, then select it and try to import it into that course?

[danysvnt]

Do you mean to create a course of the same language?

[danysvnt]

And will all of my achievements disappear?

[zoran]

No, that won’t affect anything. The error message in your screenshot shows that you can’t import content into that specific existing course. If you create a new course and import lessons into it, it should work.
