error importing rss feeds from message boards

[Joerg Schaefer, modificado 14 Anos atrás.]

Hi, i want to display message board threads as RSS feeds. If i open the rss url with firefox, everything works fine. But if i paste the url into the rss portlet i got the error message "http://localhost:8080/c/message_boards/rss?p_l_id=28590&categoryId=25597&type=rss&version=2.0&displayStyle=title cannot be found".

If i took a look into the logfile i found this:

10:46:43,218 WARN  [WebCachePoolImpl:71] com.liferay.portal.kernel.webcache.WebCacheException: http:
