Problems since last forum software update (Jan 2013) - posted messages don't always show but count of replies shows that they're there. Example:
A recent thread may show in the threads list as having 1 reply, but only the original poster's name and message
are shown. The reply doesn't appear, even after a long period of time - sometimes many hours. Standard remedies
have no effect - refresh, cache flushing, close and reopen
of browser, etc.
*But* if I post a new reply to that thread, then the invisible reply suddenly becomes visible. This is not only annoying, it
can result in replication of effort, as my reply may repeat
material already in the post from someone else that I couldn't
see before I posted.
