Slightly off-topic and apologies for using your post here but...
A few days ago, spammers found one of my sites and started up their shenanigans. As a way to mitigate the attack, I switched to, 'Administrator validation' for new registrations. This had a quirky side effect of not allowing moderators to see any new reported posts. Had me stumped as to what I may have done that made this happen. I tried switching it back to, 'Email validation', but that didn't make the reported posts show again. I became frustrated and left it alone for the rest of the day. Woke up the next day and what do you know, my moderators could see reported posts again.
I had tried clearing the site cache in the ACP the day before but that didn't work so maybe it was another task that had to run to free it up, dunno. Just glad it is working again.
