    Today I tried to update to PHP8. Unfortunately my blog does not work.
    I activated Debug mode and saw the following error:

    Fatal error: Uncaught Error: Call to undefined function create_function() in /data/web/htdocs/wp-content/plugins/wp-memory-usage/wp-memory-usage.php:108 Stack trace: #0 /data/web/htdocs/wp-settings.php(388): include_once() #1 /data/web/htdocs/wp-config.php(37): require_once(‘/data/web/…’) #2 /data/web/htdocs/wp-load.php(37): require_once(‘/data/web/…’) #3 /data/web/htdocs/wp-admin/admin.php(34): require_once(‘/data/web/…’) #4 /data/web/htdocs/wp-admin/index.php(10): require_once(‘/data/web/…’) #5 {main} thrown in /data/web/htdocs/wp-content/plugins/wp-memory-usage/wp-memory-usage.php on line 108

    Perhaps you can fix it. I hope so 🙂

    Hi Jaeger,

    This error message is caused by another plugin, not for our plugin.

    Try to deactivate this plugin:
    WP-Memory-Usage
    because it was actualized last time 7 years ago and is compatible with WordPress 3.7, not 5.6.

    Please, try our plugin wp-memory and let us know if it has some issue with PHP 8 and we will fix it quickly, if necessary.
    https://wordpress.org/plugins/wp-memory/

    Our plugin can show you the available memory too.

    To deactivate it, remove this folder:
    /data/web/htdocs/wp-content/plugins/wp-memory-usage/

    You can do it by FTP or thru your file manager on your hosting panel.

    You can also change your php to 7.x and do it, go to your
    Dashboard => Plugins => WP-Memory-Usage
    and deactivate it.

    Otherwise, request support to your hosting company to remove that folder.

    Cheers,
    Bill

    I’m very sorry about the confusion. Yes you are correct.
    And thanks a lot for the explanation how I can fix the problem.

    Unfortunately your plugin also throws and error:

    Fatal error: Uncaught Error: Call to undefined function add_management_page() in /data/htdocs/wp-content/plugins/wp-memory/wpmemory.php:180 Stack trace: #0 /data/htdocs/wp-includes/class-wp-hook.php(287): wp_memory_init(”) #1 /data/htdocs/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array) #2 /data/htdocs/wp-includes/plugin.php(484): WP_Hook->do_action(Array) #3 /data/htdocs/wp-settings.php(579): do_action(‘wp_loaded’) #4 /data/htdocs/wp-config.php(37): require_once(‘/data/web/…’) #5 /data/htdocs/wp-load.php(37): require_once(‘/data/web/…’) #6 /data/htdocs/wp-admin/admin.php(34): require_once(‘/data/web/…’) #7 /data/htdocs/wp-admin/plugins.php(10): require_once(‘/data/web/…’) #8 {main} thrown in /data/htdocs/wp-content/plugins/wp-memory/wpmemory.php on line 180

    Hi Jaeger,

    Thanks for let me know.
    I’m on London timezone. Tomorrow I will find a solution and let you know.
    I will install PHP 8 in our server and run a couple of tests.

    Thanks for the patience,
    Cheers,

    Hi Jaeger,

    I’m working on that.
    Please, check if you are running the last version of WordPress (5.6 or 5.6.1)

    Please, let me know.
    Cheers,
    Bill

    Hi Jaeger,

    The plugin works fine now (Version 1.4) with PHP 8 (tested with PHP 8.0.1)
    Just install from WordPress the version 1.4

    Thanks for the patience and for the collaboration.

    Cheers,
    Bill
