I have got a security error with this header template.

Could anyone suggest a fix?

<navigation>
<div id="header">

The instances of "{$mybb->settings['#']}".
I suggest you remove them, what are they for anyway?

I have no idea. It's a custom theme called "photoshop bliss v3".

They should be: {$mybb->settings['bburl']}

You can replace them with what you want. They are what is causing the issue.
As said above {$mybb->settings['bburl']} is what they should probably be.
Depending on what your site is you could just remove the rows that contain it.

I have changed the links and turned it into a menu. Thanks for your help.
