Hi, @BeHappy ,
This is Evita from On The Map.
If you uninstalled the app, then it's not the problem. When the app is uninstalled, then it can't access your store anymore. Can you send me your store URL? Maybe the problem is with your webserver?
This is definitely NOT an app issue, you are missing an SSL certificate. https://prnt.sc/pzgapu
You can read more here about SSL - https://help.shopify.com/en/manual/domains/managing-domains/ssl
