Error in paging

Hello.
Thank you for this plugin, it’s amazing. But I have a problem I couldn’t solve.
In paging menu, the first page works fine, but when I navigate to any other page. All pages links leads to the current page.
In first page
(Name in pages list : The link )
page 1 = pagenum=1
page 2 = pagenum=2
page 3 = pagenum=3
page 4 = pagenum=4
After navigation to any page (example: page 3)
page 1 = pagenum=3
page 2 = pagenum=3
page 3 = pagenum=3
page 4 = pagenum=3

This problem in both admin and front end panels. I tried to edit the code but I couldn’t solve it. Any solution?
Thanks
