i duno if you looked at the FAQ but have you checked about all of this?

Why can't I see the most recent version of a page? Why won't my journal or friends page update?
If you aren't seeing the most recent versions of LiveJournal pages, you are most likely viewing an old version of the page in your browser cache. Specific examples include recent updates not showing on your friends page or a message that your LiveJournal updates were successful before making any updates.
First, click your web browser's Refresh or Reload button. Next, clear your browser's cache or consult browser documentation to see if your browser provides a "hard" or "forced" refresh. For instructions on clearing your browser's cache, read your browser's documentation or the rest of this FAQ (click on "Read more" below).
If clearing your browser cache doesn't resolve the problem, you will need to investigate other reasons why entries are not showing correctly. In particular, entries marked as dated out of order will not appear on your friends page. Additionally, incorrectly formatted HTML can make your journal or friends page appear to stop updating.

also, it seems unlikely that both the people you asked would have done this, but it's possible filter your friends page. so maybe they have you in a friends group that is filtered out from showing up on their friends page?
