Hi there.
On the page "http://wiki.ontoworld.org/wiki/Help:Inline_queries" , It say "Watch out! This page describes concepts from <=0.7 that have been dropped in version >=1.0!"
I try a queriy in timeline format. It go wrong(I am using 1.0 RC2). But on the page "http://wiki.ontoworld.org/wiki/Upcoming_events", it works find.
I think it's exactly the same query. In fact, I imported some pages from ontoworld. See "". You can find the timeline page on ""
I am not sure if it's a bug in the latest SMW.

My Database structure is utf8_general_ci (like followed picture).

The error message is like followed picture.
