View generated blocks don't appear on pages...

Hi there,

Basically, I have setup some views with displays of type blocks.
The blocks are listed under the block list, but when I assign a region to them to show on the right-hand side for instance, they don't. I have also assigned the correct path for the pages where those block should show up. To be sure, I even tried displaying them on any page, and it didn't work either....

Any hints or ideas would be appreciated...

Thanks.
