I'm unable to even login to my WordPress dashboard

I actually had this issue last night and spoke to Samantha who was able to resolve it.

The error was that in my WordPress settings I had one address set to http and the other https

However, now I’m unable to even login to my WordPress dashboard and make any changes.

I connected my security certificate from Bluehost, so I went into my setting so change to “https” – which must have been a mistake, as the error happened immediately after I made that change
