This bit looks susoucious. Wrapping something in parenthesis in an ember template causes it to be treated as a helper (i.e. a function). So I think you want to drop one level of brackets there:

```diff
- <div class="category-title-name" style={{if (not (this.logoImg))
+ <div class="category-title-name" style={{if (not this.logoImg)

```

By the way, are you developing against a production instance here? If you use a development instance instead, you should get a much better error message.
