Hmm, ok, so it seems that something in the registering of celltoobar widgets and presets is going wrong, but not so wrong that it prevents the nbextension from loading completely (hence no error in console). If you're comfortable using a JavaScript console, you could try placing a breakpoint somewhere in the loading to try to see what goes wrong, but so far I'm unable to reproduce this, init_cell seems to be working ok for me...

I am not sure how to place braekpoint. However, I opened the JavaScript Console before loading the notebook and there's actually an error right after loading the init_cell ... do you know what could be happening ?

oh, it looks like you're using 0.2.6, and seeing a bug which has already been fixed in #928. You can resinstall from the git repo, or apply the fix in be593bd directly to init_cell/main.js
