I upgraded a few hours ago from 2.11 and all ok except for 1 rather strange bug.
Going into the visitor log everything seems as usual until you click on the next button (I have it at 50 entries per screen), and on the next screen it says there are no more entries (it’s not a date selection problem).
OK, so I change the no. of entries to something higher such as 100 or 500, and the entries appear, but flipped, so starting from the 500th entry at the top and the most recent entry at the bottom, the opposite to normal.
FYI,
Alex
