Menus not displaying properly with Wordpress 481

After updating to Wordpress 4.8.1 the Main Menu (top menu) is just listed down the left side of the screen including all drop downs. Is there a fix for this problem?

To fix this you need to find two lines inside the functions.php file of the theme:

<ul\sclass

and replace them with:

<ul\s+class

If you don't want to delve in code you may just download the updated version of the theme and replace the entire functions.php file located inside the theme directory on your server.

I was experiencing the same issue on Vaccination Theme and this helped!

Kind regards,
Henry
