XF 2.1 After import, latest/recent threads search is empty

[cwe]

I imported my vB 3.8 forum data into clean XF install. Import worked fine. I can browse threads, etc. Widgets that should show latest or recent threads and the search function itself do not return any results. I tried rebuilding the search index and it is still the same result. How can I get existing threads to show on the latest threads list?

If I search for a word or something, the search will show many threads in the result. The new posts widget still isn't showing anything. Is there some hard coded time window that threads must satisfy to show in the new posts widget?
