Wiki plugin does not generate wiki page

Hi, I'm using the theme bp-scholar. When I installed Wiki plugin on my computer through MAMP, the wiki plugin worked beautifully. However, when I installed the wiki plugin online through ftp, the wiki does not automatically appear on my navigation bar as it did on localhost. All the plugin admin stuff shows up, but there is no way to access the wikis that make. I tried to manually make a wiki page through Wordpress, but it's not linked to the Wiki plugin. What to do? Thanks for your help.
