Missing Argument nav_menu_css_class

Hi @rivmedia – what version of WordPress are you using?

Hey,

Latest version ( 4.5.3 ). It could be a theme or plugin conflict ( I havent checked yet ), but previous version of the plugin works fine.

I’m seeing a fix to implement for versions prior to 4.1, but I’m not getting any errors running twentysixteen with no plugins at or above 4.1. Please let me know if it ends up being a plugin/theme conflict. Thanks!

I just pushed an update to fix this. You should see the plugin update it in your Dashboard in a few minutes assuming WordPress updates it quickly. Let me know if you have any more issues.

Perfect thanks very much, all working ok now.

Great to hear!

Warning: preg_grep() expects parameter 2 to be array, boolean given in /home/yapiyoruz/public_html/wp-content/plugins/font-awesome-4-menus/n9m-font-awesome-4.php on line 216

Latest version ( 4.5.3 )

@coolwind38 – please start a new thread, but this is likely a theme or plugin conflict. The line you reference is pulling the classes from the WP Nav Menu classes. If another plugin or theme modified that, it could be causing the problem.

Can you try deactivating other plugins and switching your theme to twentysixteen, and then report back? (If you do that and still get errors, let me know what version of WordPress you’re using. Thanks!)

I face some problem, i use “Font Awesome 4 Menus” Version 4.6.3.2, I have one error which is “Warning: preg_grep() expects parameter 2 to be array, boolean given in localhost\abc\wp-content\plugins\font-awesome-4-menus\n9m-font-awesome-4.php on line 216”, please guide me what to do.

I’m sorry Muhammad Fahim. I just pushed an update with a fix for the array check (also added it in another place as well). Please let me know if/that this solves the issue and thanks for your report!
