[Plugin: WP-PageNavi] a single displayed page

Hello, I installed the plugin pagenavi, but I was only the first page displayed when there are others.
I watched a bit on the forum and checked a lot of things but nothing was done, I put in the config:

Number of pages to be displayed => 10
Number of intermediate steps to display paging => 0
View the intermediate steps in multiples of paging => 0

but at the bottom of page I only page 1 of 1.

thank you
