Support » Plugin: LifterLMS » “No HTML was returned.” error displays after each lesson

  • Resolved dilshodwordpress


    “No HTML was returned.” error displays after each lesson if a user is not logged in. If a user is logged in, “mark complete” or “take quiz” button shows up, depending if there is a quiz for the lesson or no.

    It won’t fix if I:
    1. change my theme to default Twenty Nineteen
    2. disable all plugins
    3. disable and enable LifterLms
    4. disable custom CSS

    Hi @dilshodwordpres,

    The main reason you would see a “no HTML was returned” in place of the mark complete button on a lesson is if the lesson is set to free and you are viewing it as not enrolled/registered in the course.

    The reason for this is because we do not have a way to track non-users/non-enrolled students in courses even if the lesson itself is free.

    You can hide this by setting the “mark complete” block to visible only to enrolled students in that course.

    I hope this helps,

    Let us know if you have any further questions!

    Thanks and take care,

    Indeed, it solved the problem, in the lesson options you can do that. Thank you very much. Only one suggestion, is it possible to make it work as visible to enrolled people only by default? Because it’s 3 more clicks every time you make your thousand lessons.

    This is a known issue which we’re aiming to resolve in a future release.

    You can track our progress on getting this fixed in this issue report:

    Thanks for your patience

    and if possible, please add an option to view quiz button for all users regardless they pay or not enrolled or not. This can make your site a good resource wiki-like site, which adds up to the functionality just to use it as LMS only. Don’t you think it’s really cool and users really want this?
