OK, Len. Tell me how you are viewing the forum posts. (I normally click on "What's New" at the red bar to read what has come on here since I've last been on the forum.)
For instance, I can click on the Forum: General RVing and see a list of posts. Down about the 15th post (assuming no posts added after I write this) there is a post titled "Mattress ... " for December 13th. The list continues with a list of posts after that post. "rjf7g" also managed to reply to that post somehow, but I can't read either post.
Len, please explain what you mean by "... It is blocking viewing any threads older than the one with the dots...."
If we keep at this, then we might gather enough information for the "programmers" to work on a solution.
