WP update 48 brakes menu

Hello,

I just did the Wordpress Update 4.8 and suddenly my whole menu is broken up with my theme Tank. It doesn't show like it should be. Anybody else with the same problem?

Does the theme need an update too?

This is how it looks right now: http://imgur.com/a/lmUY9

Yes, other themes menu wrong

Downgrade WordPress 4.7 and perfect appearance.

Here is a screenshot of faulty texture:

ohh, not good
only menu

Same here, went back to 4.7, please provide a fix. Thanks

Hi!

The latest WordPress update has changed the menu structure, that's why we had already updated our themes. You may download the updated version or fix the issue manually. To fix this you need just to find two lines inside the functions.php file of the theme:

<ul\sclass

and replace them with:

<ul\s+class

The functions.php file located inside the theme directory on your server.
