On one of my network sites, the tagline is set to one thing but when I access the live site, it's another. It may have something to do with Smartcrawl maybe but I'm getting an access denied error (I'm the Super Admin). No idea why.
The attached image is the backend of the site and you see the tab (arrow pointing to it) of the live site. That tagline in the tab is that of my main network site.
