Elegant Themes – Divi – Page Pagination in blog module not working

I have downloaded the Divi theme 2.3.1 from Elegant Themes and the latest wordpress 4.1.1 with plugin wp-pagenavi and use divi booster to help me to make page builder appear in post page. All was going well, I loved the theme. After a while i got an error with pagination in homepage that created by page builder.

I used divi 2.3.1 and make homepage with blog module from page builder, and also use divi booster to add page builder for post page. the problem is i got a problem in pagination with or without wp-pagenavi when i click older post or older page, the url is changed but the content or indeks still in page one and the apperiance goes to standar view with sidebar. please tell me how to resolve this problem. thanks for your attention and help. my webpage is diviwallpaper.com

Any ideas?
