I have a little slogan in there that I need to change and I can’t for the life of me figure out where I changed this. 

Are you referring to the title on the page, or title in the browser there?

The title in the browser. I need to update it, but just can’t see where I did it before. 

You would be looking to change the meta tagsin that case. Take a look here
