Question disappears on vote submit (again)

Hi quicksketch, I have the disappearing content issue again. Went through the other issues but nothing there seemed to be a solution for this case.

As an everlasting newby I am trying to port our old site to D6 at new.globalopinion.eu trying to maintain as much of the former functionality as possible. There was some custom coding to show the result-block in a different way, and the pro-con module is integrated.
And unfortunately we now have what others had before, content (question) disappears after voting, although the results do appear. This happens both in teaser as in node. First I thought maybe some influence by the tweet, and facebook buttons, but they don't appear on the teaser so I discarted that. Same goes for pro-con content. Only the rating on the poll itself appears on the teaser.
After refresh everything is ok. Page compression, block cache and optimize javascript are enabled (somewhere you talk about enabling "all" caches, what/where's that?)

I Include screenshots with the firebug windows open: before voting, after voting and after refresh after voting. You can see that the divs for content after voting simply don't appear... Any suggestions? You can also try for yourself if you want.

By the way, without ajax poll installed, we had a problem on the teaser page. Votes went to the first item in the list instead of the poll you voted on (say 4th poll). So there was already something strange there. This behaviour has disappeared with ajax poll.

By the way II - there does seem to be some js problem on the site: js directories or files seem not to be created (sometimes...) and when updating a view I get this blank page with a lot of text/coding instead of remaining/going back to the view-edit form, so there I have to hit "back" to be able to save. And then the changes turn out to have been executed. Don't know what to do with that either, but it's kinda working.

tnx
