[TxMt] Blogging bundle query

[Nigel Green]

Hi all,

Apologies if this is an old query, but I've tried finding the answer in the archives and nothing seems to fit with what I need.

I have set up my blog and can post entries and edit entries just fine, but if I try and add a category (using the "tab-cat" snippet) then I get an error message: 

"Received exception:Wrong type NilClass. Not allowed!
No categories are available!"

Does anyone know why this might happen with categories when I can access posts remotely?

Many thanks,
Nigel
