I has changed host for pligg, files and database have been moved without any problem.
But after open website from new host, Published news in the first page is not showing anying. Upcoming news shows without problem only the first page that is not show.
After I login as , Published news in the first page shows. So I think problem is not coming from database but must be something else. I try to delete cache in template_c folder but Published news still not show if i'm not login.
