Could you provide a little more detail about the issue you’re encountering?

I’m not sure what was meant by “this started when personal came online”.

Safari does not have a login. Websites can have logins, of course.

Safari will (by default) block insecure connections to websites.

There is a means to disable that block, but I’d be hesitant to enable that particularly with a website needing a login.

The preferred solution is to fix the website connection to be secure. The best solution may involve a discussion with the website administrator, as well. Though a workaround is potentially available.
