Error 404-Page NOT Found (Remove Blog Section from Front Page)

I recently set up a website using your theme Clean Journal. I love how it's enabled me to achieve a streamlined and professional look for my online writing service, Wrote-IT.ca. But there's a catch: a 404 error message that pops up on the bottom of the screen where the blog content should be. I don't have blog content yet -- it's something I plan to add at a later date. I wondered if for the interim, there was a way to remove the Blog Section from the landing page so the 404 error does not show. Is there a way to do that? I've spent time looking for a solution but had little luck so far. Please help! Thanks.
