    I have 2 websites on which i recently installed Lifter LMS.
    One of those websites has the GP Premium Theme.
    Today i couldn’t loging on BOTH of my websites anymore ; had to arrange the host to be able to log in again….
    Today i updated the Lifter LMS plugin ; that caused the break down.
    The failures to be seen were :

    Fatal error: Can’t use method return value in write context in /home/xxx/public_html/wp-content/plugins/lifterlms/includes/models/model.llms.question.php on line 406

    Fatal error: Call to undefined function is_user_logged_in() in /home/xxx/wp-content/mu-plugins/endurance-page-cache.php on line 370

    Do you know about these problems ?

    As i use 2 websites and two respectable themes (one is GP Premium) and on both i upgraded the Lifter LMS Plugin, the fault may be lying there obviously.
    I already put my question there as well, but do you know what happens here, and what to do about it ?
    Because Lifter LMS is the only plugin which really serves my needs, i must keep it…..

    Hope to hear from you,

    Hi Mar,

    From the error it looks like their end of the problems.

    Did the same errors occur for both themes? If so it’s likely the plugin’s problem.

    I would wait to hear back from LifterLMS first.


    Ok Leo,
    Thought so.
    Yes, the errors occurred on both themes but 2 on the first and 1 (same) on the second.
