Dear Triggeru,
There is an ajax request made to save the pagination settings. If its returning 0 there has to be a problem. First try to enable WP_DEBUG in wp-config.php like explained here:
http://wp-types.com/documentation/user-guides/debugging-types-and-views/
Then go through the processing of saving pagination settings and see if it generates error messages and post them here.
Regards,
Caridad
