Mods - threads are disappearing for me (with the new changes to the website?).

A few days ago I posted a new thread in the Off Topic section called "Workaround for Sony wireless speaker "(close). It never showed up under new posts but could be found only by doing a search under tyl604.

I posted a new thread called "Where is my post?" a day or two ago. It never showed up either.

Today I saw a response to the second thread which said something like "is this it?" Diseasel300 says he can see it and asks why I cannot see it.

Now that thread and response is gone; cannot find it anyplace without using the Search function; should be in new posts but is not showing. Thread #2 and Thread #1 are still nowhere to be found except by using the Search function.

Any idea what is the problem? Are others having the same problem?
