Warning: call_user_func_array()

  • I have duplicated my WordPress website to a new domain.
    Everything works fine, the only thing is there’s a warning on top of my website that says:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘wpt_register_css’ not found or invalid function name in /public/sites/www.imaverick.nl/wp-includes/plugin.php on line 525

    If I delete line 525 in the plugin.php the whole css of mij /wp-admin disappears.
    Anyone who know what to do?

    my website is: https://imaverick.nl/

  • Hi rickvanleeuwen,

    Can you try by deactivating your site’s plugins one by one and find out which plugin is the culprit ?

    I guess the problem here with the version compatibility.

    I only have two plugins on my website. The Warning stays when I deactivate them.
    Do you have other ideas?
