Jcarousel doesent work...

I'm sorry but this is not nearly enough information to provide help of any kind.

I just update from 6.x-2.3 to 6.x-2.4, and found views with jcarousel display enabled won't show anything.

They display as empty views, I tried add some empty text (like 'No rows') and views show 'No rows' in results.
Switch to another display would show results properly, then replace jcarousel module with previous version (2.3), it works as normal.

Although I couldn't trace back to root of problem, but this maybe a little hint, thank you.

Same problem here. The view is returning results, but only the empty text is being displayed.

EDIT: scratch that, just needed to clear the cache after updating the module.

@aimakun: Did you ever solve the problem? I suspect that flushing the caches (as mrfelton did) would likely solve the problem.
