[Plugin: Just One Category] Stopped working with WP 3.1

Having the same issue… after WP upgrade your awesome Just One Category plugin does not work as it should.

I know it is your personal time and energy you put into this. Can you at least comment if an update is expected or shall I roll back to 3.0.5 of WP?

Hi, I wrote a hotfix, that makes Just One Category running on WordPress 3.1. Hope you enjoy.

Unfortunately that does not seem to work in 3.2.1 – I just tried it, and the subcategory posts are still showing up in the parent categories. Making the change didn’t generate any errors or anything – it just didn’t seem to have any effect.

The hotfix doesn’t work with WordPress 3.2.1 and I have not time and interest to solve the new problem. Sorry.

I consider this a temporary fix but try this with 3.3: Just One Category
