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 is correct
