Problem:
Option to change number of posts per page when using archive

Solution:
The 'wpv_filter_query' hook will work for views not for archives. If you want to filter archive query arguments on fly either you will have to use pre_get_posts hook or the 'wpv_action_apply_archive_query_settings' hook.'

You can find proposed solution in this case with the following reply:
