 * Hi,
    If anyone knows how to fix an error in the error_log, I would greatly appreciate
   it. This one error seems to log about a hundred times a day:
 * [16-Dec-2018 15:18:25 UTC] PHP Warning: Missing argument 4 for FLLayout::filter_nav_menu_link_classes(),
   called in /home/txm9ymah4c5o/public_html/wp-includes/class-wp-hook.php on line
   286 and defined in /home/txm9ymah4c5o/public_html/wp-content/themes/bb-theme/
   classes/class-fl-layout.php on line 288
 * Is this because the syntax is wrong?? This is my first time trying to fix an 
   error, but I am familiar with the files and modifying code.
 * Thanks,
    Cindy

 * I see some references to what might possibly be an issue with the current theme.

 * The site appears to be using the Beaver Builder Theme, Version: 1.7.1.1. Due 
   to the commercial nature of the theme, you may want to contact support at Beaver
   Builder and inquire about any known issues. It might be something as simple as
   a theme update or a known issue they can help with.

 * Beaver Builder theme does indeed use that filter and it correctly passes four
   args to the filter, other plugins do not. Weve seen this come up a few times 
   recently, latest was the wp mobile menu plugin which was also using the same 
   filter and only passing ONE arg to the filter.

 * Hi Clayton and Simon,
 * You two are correct. It is a Beaver Builder theme and we’re also using their 
   builder. I did not know where to begin with trying to address this error. They
   have great support, so I will contact them. Was thinking this is my error because
   I can see it lol 🙂
 * Thank you both for the help!! I didn’t think anyone would really be on the forums….
   I am very grateful for your kindness!! Happy holidays to you all! 🙂

 * Well Beaver Builder support will tell you exactly what I have already told you,
   the bb theme is not doing anything wrong, it uses all four of the args for that
   filter, I can show you the code from the theme…
 * `add_filter( 'nav_menu_css_class', __CLASS__ . '::filter_nav_menu_item_classes',
   999, 4 );`
 * and the function: `static public function filter_nav_menu_item_classes( $classes,
   $item, $args, $depth ) { ... }`
 * As you can see *four* args passed by the filter and *four* are there in the function.
 * Another plugin is using the same filter with the wrong amount of args.
 * If you disable other plugins you will see the error go away and find the plugin
   that is doing it wrong.
