Method "currentAncestor" for object "Knp\Menu\MenuItem" does not exist in Sonata

Question

I'm new to Symfony2 and I just installed it along with fosUserBUndle 1.3.3, Sonata Admin BUndle, and Sonata User BUndle. Now I get an error that I cannot resolve.

Here is my error:

(url localhost:8000/profile/ ) :

Method "currentAncestor" for object "Knp\Menu\MenuItem" does not exist in 

SonataBlockBundle:Block:block_side_menu_template.html.twig at line 29

I am able to login succesfully, but I get this error after login. Any help would be greatly appreciated.

Thanks

open file block_side_menu_template.html.twig at /var/www/html/MySymProject/vendor/sonata-project/block-bundle/Resources/views/Block/block_side_menu_template.html.twig

look at line 22 :

{%- if item.current %}
{%- set classes = classes|merge([options.currentClass]) %}
{%- elseif item.currentAncestor %}
{%- set classes = classes|merge([options.ancestorClass]) %}
{%- endif %}

Edit to :

{%- if matcher.isCurrent(item) %}
{%- set classes = classes|merge([options.currentClass]) %}
{%- elseif matcher.isAncestor(item, options.depth) %} 
{%- set classes = classes|merge([options.ancestorClass]) %}
{%- endif %}
