[TYPO3-ttnews] tt_news does not display at all (except on one page)

[wowbagger]

Dear list,

     I've got a very uncommon problem with the tt_news extension and I'm 
running out of ideas. Only the first page loaded after the caches are 
cleared is working - all other pages with tt_news plugins fail. The 
following problem is reproduceable at any time:

clearing all caches in the backend
loading the start page > several tt_news content plug-ins with different 
pids (pages not sys-folders) work just fine as well as the rss-feed
loading the press page > none of the tt_news content plug-ins shows any 
output
clearing all caches in the backend
loading the press page > all tt_news content plug-ins on that page are 
working fine now
loading the start page > no output from any of the tt_news content 
plug-ins and the rss doesn't work (xml-error: no element found)

I've taken over support of a huge web-project and updated the whole system.

TYPO3 4.1.1 > 4.5.22
tt_news 2.5.0 > 3.4.0 (update script didn't show)

I'm glad if any of you could give me any suggestion how to solve the 
problem. I'd gladly post any further details about the configuration.

Thanks in advance, bbb
