Issue with Hueman Theme – Header problem

Hello

Any help on this would be much appreciated. I started working on the Hueman Lite version of the theme today and had just done some basics, set up pages and a menu when I came across the full version on Github.

So I installed the zip file to use the full version but when I activated it I got 5 lines appearing in the header like this

Warning: Illegal string offset ‘background-color’ in (path name)/wp-content/themes/hueman-master/functions/dynamic-styles.php on line 230

There are several entries like this almost identical relating to background, size, image etc up to line 235.

I’m no CSS programmer but if someone can point me in the right direction I can edit files.

Before you ask, I tried deleting the lite and full version and then re-installing the full one but with the same result.

As I said any help would be appreciated as I think this theme looks pretty good.

Thanks

Colin
