New Nine on "[Plugin: Font Awesome 4 Menus] Missing Argument for FontAwesomeFour"

The new update of your plugin (4.6.3.1) is showing error messages in my site's header:

Waing: Missing argument 4 for FontAwesomeFour::nav_menu_css_class() in /home/***/public_html/wp-content/plugins/font-awesome-4-menus/n9m-font-awesome-4.php on line 134

There's 6 messages like this one. I'm using Newspaper Theme by tagDiv.
This is the first time I have an issue with your plugin and I really like it, it would be great if you could update it again with a fix for this issue :)

Thank you in advance!

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.

It fixed the issue, thank you very much!

Glad to hear!

I just did an update to font awesome plugin, its now generating following error:

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

Can you please suggest the solution?

I'm sorry bikram_068. I just pushed an update with the above 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!
