page navi is off

I am not sure exactly how to correct this problem but my designer installed the plug in for page-navi when I look at the home page of the blog its appears fine up until page 7. From that point on my page numbers are smashing together on the rest of the pages. I only have 15 posted right now.

Number Of Larger Page Numbers To Show? I have zero here to disable, previously “3” and it makes difference either.

Show Larger Page Numbers In Multiples Of: 5 is supposed to display in that increment and it doesn’t no matter what I do

I don’t understand how to plug in works.
