PHP Warning

  • Hi

    I do not use your plugin anymore but if I uninstall and remove it, my file error_log is full of this message :

    [08-Feb-2021 09:34:15 UTC] PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘simple_css_generate’ not found or invalid function name in /home/misite/public_html/wp-includes/class-wp-hook.php on line 287

    Thanks
