    Hello,

    I have this error on my website since recently : 

    
Fatal error: Uncaught Error: Call to undefined function is_user_logged_in() in /homepages/44/d848188129/htdocs/clickandbuilds/studiopepi/wp-content/plugins/wp-speed-of-light/inc/caches/file-page-cache.php:252 Stack trace: #0 [internal function]: wpsol_cache('<!DOCTYPE html>...', 9) #1 /homepages/44/d848188129/htdocs/clickandbuilds/studiopepi/wp-includes/functions.php(4755): ob_end_flush() #2 /homepages/44/d848188129/htdocs/clickandbuilds/studiopepi/wp-includes/class-wp-hook.php(287): wp_ob_end_flush_all('') #3 /homepages/44/d848188129/htdocs/clickandbuilds/studiopepi/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters('', Array) #4 /homepages/44/d848188129/htdocs/clickandbuilds/studiopepi/wp-includes/plugin.php(484): WP_Hook->do_action(Array) #5 /homepages/44/d848188129/htdocs/clickandbuilds/studiopepi/wp-includes/load.php(1052): do_action('shutdown') #6 [internal function]: shutdown_action_hook() #7 {main} thrown in /homepages/44/d848188129/htdocs/clickandbuilds/studiopepi/wp-content/plugins/wp-speed-of-light/inc/caches/file-page-cache.php on line 252

    Here is the link : https://studiopepi.fr/

    I think it comes from a recent update.

    Hi,

    I see the plugin is still enabled on your website.
    Where can I see the error? Is there a specific page or configuration?

    Cheers,

    Hi,

    The plugin is still enabled indeed.
    The error appears at the very bottom of the page, under the footer.

    Hi,

    I’m not sure why this error occurs. I would need to run some tests, if I can’t reproduce that I may ask you to post a support request.

    Could you disable others plugins one by one > clean cache and see if the error is still there?

    Also can you make a screenshot of the screen Speed Optimization > System Check

    Thanks.

    Here is my system check :

    This problem only occurs on this website, whereas on my other websites there is no error.
    Maybe it is caused by the fact that I use the function is_user_logged_in() in my child theme functions.php.

    But for whatever reason, the problem seems to be resolved. I don’t know why to be honest but well…

    Hi,

    For some reason the function was called too early before the logic plugin is called. Could you please use our contact from our website (JoomUnited) to get in touch because I need additional information about the website, I can’t replicate the issue.

    Cheers,
