Question about the titile of my site

Okay,when you look at the top of your browser,it will say like Your site Free Forum:

Well,I removed the Free Forum part,but you can still see it?

How can I fix this? it doesnt show in my Admin panel,but it shows when your on my site

Where have you modified this? The text at the very top bar of your browser is constructed as following:

"Site Name - Homepage Name"

Both options can be changed in General >> Configuration.

I did both-I realized what the problem was.I used a custom domain I purchased and it hasnt updated yet
