[Plugin: WP Custom Fields Search] Page 2 Issue – sometimes

When searching and selecting an option in one or more fields, I get results but the next page link gets a “not found” error
and the url looks like thishttp://eliteretreatdemexico.com/page/2/?search-class=DB_CustomSearch_Widget-db_customsearch_widget&widget_number=preset-1&cs-Resort-0=MontecristoEstatesbyPuebloBonito&cs-city-1&cs-unit_type-2&cs-bedrooms-3=0&cs-bathrooms-4=0&cs-Price_Range-5&cs-all-6&search=Search

The plugin works fine as long as I don’t select any of the fields and the url looks like thishttp://eliteretreatdemexico.com/page/2/?search-class=DB_CustomSearch_Widget-db_customsearch_widget&widget_number=preset-1&cs-Resort-0=Montecristo+Estates+by+Pueblo+Bonito&cs-city-1&cs-unit_type-2&cs-bedrooms-3=0&cs-bathrooms-4=0&cs-Price_Range-5&cs-all-6&search=Search

As previously suggested I changed the form action in searchform.php
<form method="get" id="searchform" action="<?php echo home_url();?>/">

but it still didn’t work.

then I changed the permalinks to “default” it works fine. But I want pretty permalinks.

Suggestions?
