I'm going to ask. What is it?
It's a small exoskeleton species - common varieties are cockroaches and ants.
Kidding aside, I HAVE found a bug. Pretty minor, but see if you can recreate it yourself.
On iPad, go into unread topics (assuming there are a few since last view). Click on one, and then instead of hitting 'Recent Unread Topics' again, just hit the back button in the Safari browser instead.
Most of the time I get this message 'SELECT command denied to user 'fonewizard'@'localhost' for table 'smf_settings'.
If I hit reload, the unread page loads fine after that.
This happens some/most of the time, but not all.
As usual, as I am far from the biggest techie here, so if it is likely at my end, let me know.
