I'm not really sure what that's supposed to mean, but all mature blocks have been paid out. You might direct your attention to "Pool Blocks" page - there are quite a few orphans due to the lower hashrate on the pool vs. the network. I'd also recommend confirming that you are using the miner posted after the fork. If you are using an old miner, you're submitting invalid shares.

Along those lines - server has plenty of capacity for more miners in case you guys are getting slower results elsewhere. Feel free to drop some hash on me.
