POW doesn't work right now because there was no PODC block yesterday and consequently all CPIDs are "invalid". This is a problem that has been discussed before, but I don't think there was a solution implemented.
In a couple of hours (after block 49405) everything should be fine.

I deactivated the hard solution checking, so that users see more solutions/shares on their accounts until the next podc superblock has arrived. Indeed, that won't bring more blocks, as the 15 minute rule is still part of the blockchain.
