I have a really weird problem. As part of trying to upgrade from 3.6.4 to 3.8.7, 4.2.0, or 5.0.0, whatever I can get to work, I've created a duplicate copy of the live site to work on. For some reason now the 'Latest Messages Posted' section of the live, original site is never updated; but anything posted on the live site, shows up on the copy under 'Latest Messages Posted'... The posts themselves however, do not exist on the copy, only the live site...
