Conflict with Wodpress

Hi there, i have a problems with WordPress setttings when im using Your plugin. I can’t change a number of post displayed on my blog page. This value is overwritten by Pagination settings! I want to have unlimited product in my catalog main page and 8 new posts on my blog page but i can’t because if i set 0 in Pagination area i see only 1 post on my blog page, if i set 6 in Pagination, i see 6 post on my blog page! I’m using Good Inc. theme, please help me because i like and need Your plugin on my page.
