    Hello,

    Our client has a multisite where the following error appeared on the German and Italian versions:

    Deprecated: Function create_function() is deprecated in /srv/www/dia/dia.aau.at/html/staging1/wp-content/themes/enfold-child_de/functions.php on line 135

    As a precaution, we generated a staging page and updated the entire pages. After the theme was finished and WordPress was also updated to 6.3, the aforementioned error message remained and another one appeared on every page and also in the backend:

    Deprecated: Function Class avia_style_generator was called with an argument that is deprecated since version 5.3! Trying to set protected/private property: avia_style_generator::print_extra_output – will become unavailable in a future release. Check for a set method or a filter. in /srv/www/dia/dia.aau.at/html/staging1/wp-includes/functions.php on line 5737

    How can you fix these errors?
    Thank you in advance.

    Hey pirkerandrea,

    The first warning is generated from your child theme, please refer to the code on line 135 in functions.php.

    I’m not sure of the second warning though. Which version of the theme and PHP are you running?

    Best regards,
    Rikard

    Hello Rikard,

    The Theme Version is 5.6.5 and PHP is 7.4.

    Best regards.

    Hi,

    Thanks for the update. What happens if you update your PHP version to 8.x? Also, do the warnings appear if you activate the parent theme?

    Best regards,
    Rikard

    Hello,
    we are in the process of updating the PHP version. I will get back to you when this is complete.

    To revisit the first problem from the first message. The line on the respective pages says the following:

    add_filter(‘pre_site_transient_update_core’, create_function(‘$a’, “return null;”));

    What exactly is there to do?
    Best regards

    We have just been informed that it is not possible to use a different PHP version.
    Kind regards

    Hi,

    Thanks for the update. The PHP version you are running is going to be obsolete soon, so you might want to change your hosting provider if 7.4 is the only PHP version they are offering.

    You can easily check if the warnings are generated from your child theme by simply activating the parent theme. We can’t be responsible for custom code added to a child theme unfortunately. Maybe you could reach out to the person who wrote or added the code in question? https://www.php.net/manual/en/function.create-function.php

    Best regards,
    Rikard
