netkingZ Hi, what version of bazaar are you working with?

luceos
i worked with :
- Flarum 0.1.0 Beta6
- Bazaar last version

@luceos
Can you help me?
Thanks

EDIT:

Ok i have fixed!
Problem is italian language package isn't compatible with Bazaar ext.
I disable italian language and re-installed Bazaar.

I have an other problem:
Why i have all write wrong?
For example : flagrow-bazaar.admin.page.button.connectDescription
Thanks you
