[TYPO3-ttnews] Strange problem with tt_news v3.0.1

[Michal Krypczyk]

Hi,

I'm working on a site where for the first time tt_news behaves strange (FE).
When the cache is cleared I can view the news items on one page in the frontend, 
but when I open another page with news plugin... there's nothing in it.
No tt_news content is being generated.

I guess it may be caused by another extension or new caching from tt_news.

Any help would be appreciated.

Regards,
Michał
