We appreciate the efforts being made, but What's New is not the same as New Posts.I moved your post here since we already have a thread on this. The site owner is working on the problem. The new posts feature was switched off to enable the board to function again (and that clearly worked), but the plan is to go to a solution that allows switching the New Posts button back on. Meanwhile, one can use the What's New button as a substitute.
It's just a poor substitute.
What's New list may show two or more posts from the same thread if they are new, whereas New Posts list was showing the threads with new posts.
Anyway, we show patience and we are waiting for the best!
