Make sure you update your namespaces, we changed the Bundles namespace from
Mopa\BootstrapBundle
to
Mopa\Bundle\BootstrapBundle
You must change the namespace references in:
* app/AppKernel.php
* Your code making use of any MopaBootstrapBundle classes (e.g. Navbar, MenuBuilder, etc.)
* Configuration referencing any classes (e.g. service definitions for menu, navbar, etc.)
For info about the branches read https://github.com/phiamo/MopaBootstrapBundle/wiki/Branches-&-Versions
If you dont want to care about the twitter/bootstrap dependency, please make sure your [composer.json](https://github.com/phiamo/MopaBootstrapBundle/blob/master/Resources/doc/including_bootstrap.md) is correct
