It’s definitely a problem with plusone, not with addthis, because even the simple google plusone code won’t work…
I’ve tried to make a static page from the source, stripped it from the code of Collapsing categories (which has a lot of references to “jquery”) and +1 button did show!
I’ve then tried disabling collapsing categories as well as other plugins on my blog, but still no luck…
Thank you for the answer, the following plugins are active on my blog
- Add Post Footer

- KB Advanced RSS Widget
- Remove Header Generator
- Simple Facebook Connect

I’ve tried disabling one by one, but still no luck…
