I joined for information about the 2014 wordpress theme

I have the wordpress plugin Custom Category Pages installed on the 2014 theme. It is activated. When I go to plugin>custom category>decorative concrete driveway and check the category it shows that it is assigned to wpccp. That says it should be active. I open the post>category>decorative concrete driveway and it shows that it is built into wpccp and updated. When I open the home page and click on the category it show a page that says content not found. When I hover over the category it shows the content as a dropdown/child. I want the category to BE the page I post all the content to. I thought that is what wpccp was supposed to do. What am I doing wrong?
