'piwik_archive_numeric_2014_12' not found. (no replies)

Hello. I did an upgrade to Piwik recently and now most of the pages display this error. The visitor log still works, but none of the other stats pages.

ERROR VisitsSummary[2014-12-19 20:57:27] [08786] Failed to get data from API: Sequence 'piwik_archive_numeric_2014_12' not found.#0 /home/earrame_vps/seawingdesigns.com/piwik/core/DataAccess/Model.

What should I do to fix it?
