The "Load More" buttons under "Hot Topics" and "Latest Posts" seem to have some problem. Most of the time they work, but, sporadically (and thus difficult to diagnose) they don't: refusing to do anything at all.
"Load More" has a timeout. If you refresh the screen they work again for maybe 5 minutes.
Along similar lines, using the browser "back" button seems to confuse the hot topics button. Often times, it will continue to say "recent posts" but will actually be displaying "hot topics".
Thank you. I'll ask the vendor to help me look into this.
