I just wanted to say that we also have this problem with a blog that we are running. We are using it in 'Multi-site' mode and have a small number of blogs hosted through the same system.
Live Blog Entries are listed correctly on the 'home blog' for the site but posted entries do not appear, as with joshuatuscan above. The header and footer of the table are pressed together (normally, there would at least be a 'no-entries' row). The links above the table are showing that posts exist.
Any advice would be greatly received.
