Hi, since last update (v3.4.0), the archives pages stop loading at function execution in the templates, so what's before shows up, what's after do not.
The first page shows up normally, the following (>= 2) not
Clearing cache doesn't solve the problem
Deactivating Breadcrumb plugin make things go normal
With the previous I hadn't had this probleme at all
config: wp 2.8.6, wp super cache and a bunch of other plugins
Hope it helps
