A couple glitchy things after installing theme?

Hello, After just installing this beautiful theme and creating also a child theme for it...I've noticed a couple problems that I've never seen before. 1. First, there was an issue suddenly with all images on my site not appearing on the 'front-end'. This seems to just happen suddenly not long after having the theme activated for the first time. Not sure what happened. My first concern was all the outdated plugins...so I deactivated all plugins and the problem didn't go away. Then I just restored my whole home database files and that fixed it. However I was testing some things by switching from a previously installed theme and back to gridalicious and when I switch back to the theme the images again were not appearing on the front-end. I clicked 'reset all theme settings' in the cusomize tab and the problem went away. It concerns me though. I don't want to encounter this problem again when I have my whole site formatted for this new theme later. I'm a little suspicious there is something going on with this theme? 2. The other thing I noticed that just started happening after installing gridalicious is in the 'bookmarking tabs'...the ones at the top of the screen that show the title of each website that is opened in a window....usually it shows my wordpress site title: and tagline (INNER FIRE: jUST keep the fire burning). But now it is only showing my title (INNER FIRE). I don't like that! I want it back the way it was! Please help!
