Same here... We're still seeing problems.  I initially cleared the cache and that worked.  Now, however, we're seeing more problems and clearing the cache doesn't help.  I want to turn caching off, but every time I change the setting and hit the update link, the host settings page reloads with my old cache value.  I discovered I am unable to change other properties on this page too.  For example, I unchecked the "disable users online" box and hit update.  When the page refreshed, the box was checked again.

Does anyone have other ideas?
