Forum threads suddenly getting sorted by views by default

[firebush03]

I hope this doesn't come across as condescending or anything... but have you already tried clicking on the "Last Post" button (see the top right of Bandorr's screenshot). The downward arrow in your screenshot is over the "Views" column so just checking. (Though judging by your wording of "it reverts back to date when I go to next page," sounds to me like you already tried this.)
