CKeditor don't align text and images

Hello.

I use the web2py framework, with Bootstrap 2.3.

http://www.web2py.com/

For this framework there is a CKeditor plugin, with CKeditor 3.6.1.

When I change the text align attribute the algn is effective iside CKeditor.

In my website, text is always at left.

Someone knows how I can resolve it ?

Regards.
