My website is throwing random 404 errors

[dwyszomi]

Hi, I got a report from a user that they were getting 404 errors when using our website.  www.blackridgeswimclub.org.  When I try to access it, I am also getting 404 errors on every other click.  Then when I refresh, the page comes up.  But our users are not able to purchase items from our site because of the errors.  Can you help?

Hi.    @dwyszomi   your site is HTTPS     forget any idea that ur site is http.   

Make sure u submit a new sitemap dot xml    as https  and do all the google analytics, google search console 

Seems like it is not forwarding automatically   from http to https
