Website active here...but it does'nt come up anywhere else- error 404!(internet

Maybe its DNS… do I have them going too many places? I’m guessing I pointed this site…PerrySenn.com to a sales/checkout cart - and my membership didn’t get paid…
I hope to find which records or DNS settings to change -
I am NOT USING the WordPress platform _
Now.Site… and have it function as a real webpage…
