Homepage displaying 404 error

Hi — I’m having problems with my site’s homepage displaying a 404 error. All of the other pages on the site are working fine. Plugins are updated and the site is backed up. The domain and web hosting do not need to be renewed anytime soon. I heard that the Google Analytics plugin sometimes causes problems, but I have never used that plugin before. Any idea how to go about troubleshooting this? Thanks in advance!
