We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
I can see "ORDER BY t_cascading DESC,t_pinned DESC,t_cache_last_time DESC" goes into the cns_render_forumview function but not through to cns_get_forum_view, even though the $sql_sup & $sql_sup_order_by parameters are passed through without changes.
This suggests sources/cns_forumview.php is altered.
The stack trace shows it as non-overridden, but possibly that's due to the way you've overridden it (per-function override?).
Here's the commit where the changes were made so you can see what may need changing in overrides:
https://github.com/ocproducts/composr/commit/cc12ba513bba98470c46c9ab9df8cbc37306d74d#diff-b5d6972d58c1fcf3a46a522925df290c
Unfortunately sometimes we do have to change compatibility within internal files in patch releases, overrides always come with a risk.

I made the changes in your commit and now it's working. Thanks!
