Can't Save 'associations' When Creating Products

[iambaz]

I'm running v 1.6 and I've been doing some work on my site and have used a purchased template which might have caused this issue. 

 

The issue is that when I create a new product - when I fill out the Categories and click save - I get the error attached.

 

All of the data saves OK except the associations.

 

I know to debug this I'll have to switch off all modules and strip the site right back, but before I open that can of worms, does anyone have any idea what this is or why it would be happening? 

 

Thanks

It has nothing to do with your theme. It looks like a database problem (in category tables).
